[Discuss] isColorDark documentation

[elizabetdev]

Yesterday, while using the EUI utility isColorDark I had to transform hex colors to rbg because this utility only accepts rgb.

I created my own function and then I realized that EUI has an hexToRgb utility and even other color utilities. I believe they are not documented. I found them searching through the codebase.

1. Should we improve the isColorDark docs section with more examples? With one that uses the EUI hexToRgb function?

2. Or should we have a color section under utilities where isColorDark would be included among other color utilities?

Is this in JS or SASS?

Think the JS. They are essentially part of our services folder. We could document them, but my guess is that with our moves towards Chroma or Polished, we'll end up deprecating these functions. I know @thompsongl was thinking along these lines somewhere (can't find the issue)

I should have included the link 😊:

Right, #2804 gets at this. I think all new color manipulation should use chroma-js, and we're already fairly close to being able to remove the custom utilities

OK. Gonna close this out then, thinking that having these somewhat hidden for the moment makes sense.
