* update: this is actually a paid tool, so i will be skipping this, as the code highlighting function is not that important to me. If anyone finds a nice free way to do this let me know.

I have only recently been trying evernote and i love the fact you can add nice code blocks.

The issue i have is that while they seperate the code nicely, the code looks a bit boring.  

On my first google search on a resolution for this i found this page. 

https://evertool.app/

It seems to be free and you have to paste in your code into ever note, then back into the tool and then back to evernote again. I have yet to test this but will see if its a valid option, and maybe will be worth the effort.
