<color>
The <color>
CSS data type represents a color. A <color>
may also include an alpha-channel transparency value, indicating how the color should composite with its background.
A <color>
can be defined in any of the following ways:
blue
or transparent
). All existing keywords specify a color in the sRGB color space Using the RGB cubic-coordinate system (via the #-hexadecimal or the rgb()
and rgba()
functional notations). These always specify a color in the sRGB color space Using the HSL cylindrical-coordinate system (via the hsl()
and hsla()
functional notations). These always specify a color in the sRGB color space Using the HWB cylindrical-coordinate system (via the hwb()
functional notation). These always specify a color in the sRGB color space Using the LCH cylindrical coordinate system, via the lch()
functional notation. This can specify any visible color. Using the Lab coordinate system, via the lab()
functional notation. This can specify any visible color. Using the color()
functional notation, to specify a color in a variety of predefined or custom color spaces. Note: This article describes the <color>
data type in detail. To learn more about using color in HTML, see Applying color to HTML elements using CSS.
Syntax
The <color>
data type is specified using one of the options listed below.
Note: Although <color>
values are precisely defined, their actual appearance may vary (sometimes significantly) from device to device. This is because most devices are not calibrated, and some browsers do not support output devices' color profiles.
Color keywords
Color keywords are case-insensitive identifiers that represent a specific color, such as red
, blue
, black
, or lightseagreen
. Although the names more or less describes their respective colors, they are essentially artificial, without a strict rationale behind the names used.
There are a few caveats to consider when using color keywords:
HTML only recognizes the 16 basic color keywords found in CSS1, using a specific algorithm to convert unrecognized values (often to completely different colors). The other color keywords should only be used in CSS and SVG. Unlike HTML, CSS will completely ignore unknown keywords. The color keywords all represent plain, solid colors, without transparency. Several keywords are aliases for each other:aqua
/ cyan
fuchsia
/ magenta
darkgray
/ darkgrey
darkslategray
/ darkslategrey
dimgray
/ dimgrey
lightgray
/ lightgrey
lightslategray
/ lightslategrey
gray
/ grey
slategray
/ slategrey
Though many keywords have been adapted from X11, their RGB values may differ from the corresponding color on X11 systems since manufacturers sometimes tailor X11 colors to their specific hardware. Note: The list of accepted keywords has undergone many changes during the evolution of CSS:
CSS Level 1 only included 16 basic colors, called the VGA colors as they were taken from the set of displayable colors on VGA graphics cards. CSS Level 2 added theorange
keyword. Although various colors not in the specification (mostly adapted from the X11 colors list) were supported by early browsers, it wasn't until SVG 1.0 and CSS Colors Level 3 that they were formally defined. They are called the extended color keywords, the X11 colors, or the SVG colors. CSS Colors Level 4 added the rebeccapurple
keyword to honor web pioneer Eric Meyer. Specification | Keyword | RGB hex value | Live keyword |

CSS Color Module Level 4 | rebeccapurple | #663399 |
transparent
keyword
The transparent
keyword represents a fully transparent color. This makes the background behind the colored item completely visible. Technically, transparent
is a shortcut for rgba(0,0,0,0)
.
Note: To prevent unexpected behavior, such as in a <gradient>
, the current CSS spec states that transparent
should be calculated in the alpha-premultiplied color space. However, be aware that older browsers may treat it as black with an alpha value of 0
.
Note: transparent
wasn't a true color in CSS Level 2 (Revision 1). It was a special keyword that could be used instead of a regular <color>
value on two CSS properties: background
and border
. It was essentially added to allow developers to override an inherited solid color. With the advent of alpha channels in CSS Colors Level 3, transparent
was redefined as a true color. It can now be used wherever a <color>
value can be used.
currentColor
keyword
The currentColor
keyword represents the value of an element's color
property. This lets you use the color
value on properties that do not receive it by default.
If currentColor
is used as the value of the color
property, it instead takes its value from the inherited value of the color
property.
<div style="color:blue; border: 1px dashed currentColor;"> The color of this text is blue. <div style="background:currentColor; height:9px;"></div> This block is surrounded by a blue border. </div>
RGB colors
The RGB color model defines a given color in the sRGB color space according to its red, green, and blue components. An optional alpha component represents the color's transparency.
SyntaxRGB colors can be expressed through both hexadecimal (prefixed with #
) and functional (rgb()
, rgba()
) notations.
Note: As of CSS Colors Level 4, rgba()
is an alias for rgb()
. In browsers that implement the Level 4 standard, they accept the same parameters and behave the same way.
#RRGGBB[AA]
R
(red), G
(green), B
(blue), and A
(alpha) are hexadecimal characters (0–9, A–F). A
is optional. For example, #ff0000
is equivalent to #ff0000ff
.
#RGB[A]
R
(red), G
(green), B
(blue), and A
(alpha) are hexadecimal characters (0–9, A–F). A
is optional. The three-digit notation (#RGB
) is a shorter version of the six-digit form (#RRGGBB
). For example, #f09
is the same color as #ff0099
. Likewise, the four-digit RGB notation (#RGBA
) is a shorter version of the eight-digit form (#RRGGBBAA
). For example, #0f38
is the same color as #00ff3388
.
rgb[a](R, G, B[, A])
R
(red), G
(green), and B
(blue) can be either <number>
s or <percentage>
s, where the number 255
corresponds to 100%
. A
(alpha) can be a <number>
between 0
and 1
, or a <percentage>
, where the number 1
corresponds to 100%
(full opacity).
rgb[a](R G B[ / A])
CSS Colors Level 4 adds support for space-separated values in the functional notation.
HSL colors
The HSL color model defines a given color in the sRGB color space according to its hue, saturation, and lightness components. An optional alpha component represents the color's transparency.
Many designers find HSL more intuitive than RGB, since it allows hue, saturation, and lightness to each be adjusted independently. HSL can also make it easier to create a set of matching colors (such as when you want multiple shades of a single hue). However, using HSL to create color variations can produce surprising results, as it is not perceptually uniform. For example, both hsl(240 100% 50%)
and hsl(60 100% 50%)
have the same lightness, even though the former is much darker than the latter.
HSL colors are expressed through the functional hsl()
and hsla()
notations.
Note: As of CSS Colors Level 4, hsla()
is an alias for hsl()
. In browsers that implement the Level 4 standard, they accept the same parameters and behave the same way.
hsl[a](H, S, L[, A])
H
(hue) is an <angle>
of the color circle given in deg
s, rad
s, grad
s, or turn
s in CSS Color Module Level 4. When written as a unitless <number>
, it is interpreted as degrees, as specified in CSS Color Module Level 3. By definition, red=0deg=360deg, with the other colors spread around the circle, so green=120deg, blue=240deg, etc. As an <angle>
, it implicitly wraps around such that -120deg=240deg, 480deg=120deg, -1turn=1turn, etc.
S
(saturation) and L
(lightness) are percentages. 100%
saturation is completely saturated, while 0%
is completely unsaturated (gray). 100%
lightness is white, 0%
lightness is black, and 50%
lightness is "normal."
A
(alpha) can be a <number>
between 0
and 1
, or a <percentage>
, where the number 1
corresponds to 100%
(full opacity).
hsl[a](H S L[ / A])
CSS Colors Level 4 adds support for space-separated values in the functional notation.
HWB colors
Similar to HSL color model, the HWB color model defines a given color in the sRGB color space according to its hue, whiteness and blackness components.
As with HSL, HWB can be more intuitive to use than RGB. A hue is specified in the same way, followed by the amount of whiteness and blackness, respectively, in percentage values. This function also accepts a alpha value.
Note: There is no separate hwba()
function as there is with HSL, the alpha value is an optional parameter, if it is not specified an alpha value of 1 (or 100%) is used. To specify this value a forward slash (/
) must follow the blackness value before the alpha value is specified.
HWB colors are expressed through the functional hwb()
notation.
Note: The HWB function does not use commas to separate it's values as with previous color functions.
Functional notation:hwb(H W B[ / A])
Same as HSL: H
(hue) is an <angle>
of the color circle given in deg
s, rad
s, grad
s, or turn
s in CSS Color Module Level 4. When written as a unitless <number>
, it is interpreted as degrees, as specified in CSS Color Module Level 3. By definition, red=0deg=360deg, with the other colors spread around the circle, so green=120deg, blue=240deg, etc. As an <angle>
, it implicitly wraps around such that -120deg=240deg, 480deg=120deg, -1turn=1turn, etc.
W
(whiteness) and B
(blackness) are percentages. These two colors mix, so you would need 0%
whiteness and 100%
blackness to produce the color black. And vice versa 100%
whiteness and 0%
blackness for the color white. 50%
of both values renders a mid grey and any other variations a shade of the hue specified.
A
(alpha), optional, can be a <number>
between 0
and 1
, or a <percentage>
, where the number 1
corresponds to 100%
(full opacity). When specifying an alpha value it must be preceded with a forward slash (/
).
System Colors
In forced colors mode (detectable with the forced-colors media query), most colors are restricted into a user- and browser-defined palette. These system colors are exposed by the following keywords, which can be used to ensure that the rest of the page integrates well with the restricted palette. These values may also be used in other contexts, but are not widely supported by browsers.
The keywords in the following list are defined by the CSS Color Module Level 4 specification.
Note: Note that these keywords are case insensitive, but are listed here with mixed case for readability.
ActiveTextText of active links
ButtonBorderBase border color of controls
ButtonFaceBackground color of controls
ButtonTextForeground color of controls
CanvasBackground of application content or documents
CanvasTextForeground color in application content or documents
FieldBackground of input fields
FieldTextText in input fields
GrayTextForeground color for disabled items (e.g. a disabled control)

Lab colors
CSS Color 4 introduced Lab colors. Lab colors are specified via the lab()
functional notation. They are not limited to a specific color space, and can represent the entire spectrum of human vision.
LCH colors
CSS Color 4 introduced LCH colors. LCH colors are specified via the lch()
functional notation. They are not limited to a specific color space, and can represent the entire spectrum of human vision.
In fact, LCH is the polar form of Lab. It is more human friendly than Lab, as its chroma and hue components specify qualities of the desired color, as opposed to mixing. It is similar to HSL in that way, although it is far more perceptually uniform. Unlike HSL that describes both hsl(60 100% 50%)
hsl(240 100% 50%)
as having the same lightness, LCH (and Lab) correctly ascribes different lightnesses to them: the former (yellow) has an L of 97.6 and the latter (blue) an L of 29.6. Therefore, LCH can be used to create palettes across entirely different colors, with predictable results. Please note that LCH hue is not the same as HSL hue and LCH chroma is not the same as HSL saturation, although they do share some conceptual similarities.
color() colors
CSS Color 4 introduced this notation. Colors specified via the color()
function can specify a color in any of the predefined color spaces, as well as custom color spaces, defined via the @color-profile
rule.
Interpolation
In animations and gradients, <color>
values are interpolated on each of their red, green, and blue components. Each component is interpolated as a real, floating-point number. Note that interpolation of colors happens in the alpha-premultiplied sRGBA color space to prevent unexpected gray colors from appearing. In animations, the interpolation's speed is determined by the timing function.
Accessibility considerations
Some people have difficulty distinguishing colors. The WCAG 2.0 recommendation strongly advises against using color as the only means of conveying a specific message, action, or result. See Color and color contrast for more information.
Examples
Color value tester
In this example we provide a <div>
and a text input. Entering a valid color into the input causes the <div>
to adopt that color, allowing you to test our color values.
<div></div> <hr> <label for="color">Enter a valid color value:</label> <input type="text" id="color">
CSS div { width: 100%; height: 200px; }
