Thanks for taking the time to open this, @T04435.

This is a super cool idea, and the general question has come up a couple of times (like in #65 (comment) and #94). I think this ties into a suite of enhancements that I'd love to make but that I don't have the bandwidth to implement and maintain.

Currently Pika is very un-opinionated, and only represents the colours that the user picks. More complex colour management is out of scope for this app (and there are a couple of apps that already do a great job like Sip and Color Slurp).

I'd love to one day be able to dedicate the kind of time required, and I'm open to checking out PR's if anyone wants to take a pass at it. Thanks again for taking the time to make the suggestion.

You can now tweak colours until you get a result that passes. It's currently in beta, but you can grab it via the app or at https://github.com/superhighfives/pika/releases/tag/0.0.18-beta2. See more on #125.
