Can priorities be assigned to colors, the color palette re-ordered and/or colors replaced?

I've just started using this tool so I'm not familiar with how the image generation works, but would it be possible to have additional control over the color palette once a pattern has been generated, so that colors can be swapped within the palette to see how this changes the pattern? What I'm trying to do is see what effect swapping light and dark colors has to determine whether the colors look like they're receding or advancing.

Also, it would be really handy to have a control within the frontend to manually replace colors if I want to apply my own color schemes. This is not meant to make the color calculation routines redundant, just that if I want to quickly try out some different color schemes or replace a single color I would have to manually make a swatch image and upload it using the tool or bring the generated image into Photoshop and manually replace the colors.

Great software, by the way!
