RGB to RYB

Hello,

I’m working on an artistic painting application and I’m trying to offer mixing in the RYB color space for the users.

Everything concerning color in my program is using RYB values. I implemented the conversion RYB to RGB which was introduced by Gossett and Chen in their paper “Paint Inspired Color Mixing and Compositing for Visualization”. I also accomplished to figure out a good method to mix colors in RYB.

In order to integrate additional functionallity, i need to have a RGB to RYB conversion. If anybody knows how to do this, or would know how to inverse the RYB2RGB conversion, let me know. I appreciate every hint.

Thanks

It looks like this is a supplement to the paper referenced.

You could probably model it in CMYK (Subtractive) with hues of Cyan and Magenta shifted.
