Implement HLS?
Mar 9th, 2009, 10:04pm  
Would it be an idea to implement the colour system HLS? It's the one that is used in the windows colour picker rather than HSB. HLS makes more sense to me than HSB. There is Java code for converting between RGB and HLS here:

Well, Processing is an open source project, so why don't you do it and submit the patch?

It shouldn't be that hard.  My guess is that under-the-covers, Processing implements HSB in some way that transparently maps everything to RGB.  You'll just need to implement an HLS-to-RGB function, hook it in to the right places, and define another enum value so people can use it.

Yes, I'll look into doing it once I've finished this project hand-in in 2 weeks time. A colour library would be useful for things like colour schemes and complements etc.

I don't think it supports HLS but otherwise there are some quite neat colour-related functionalities in colorlib ( http://code.google.com/p/colorlib/ ).
