1. A palette of known valid color combos. Click a combo, and it populates the tool so we can see the values.
2. To see a visual indicator (a green check, yellow triangle, or red X) next to the values in the Results as they get updated.

Hi,

This tool one of the first I was using for searching best colors as web designer.

Thanks for your job.

Cool tool, tried it and it works great. To be honest I never knew there were any guidelines for this.

Put it in my favorites!

Years ago I wrote a best practise paper regarding color contrast (and luminosity and whatnot) for a freelance job, and built an excel tool for them based on your tool.

The idea was that instead of only comparing 2 colors, you could set up a matrix of foreground and background colors, and excel would tell you which combinations would pass.

It's great to see you've updated it, so I can wonder again if maybe one day I'll find the time to set this up as a web tool...

@Matthias Willerich: I've had a number of people request a "best of" list but I've always felt that a design would normally be fairly set and that people are more apt to take two values that they want to use and want to adjust across a particular spectrum to get something closer to what they want. For example, if they have a green selected, they may just want a lighter shade of green that maintains a similar RGB space. But I don't actually know how people use it so I'm just theorizing at this point.
