This fork simply limits the bit-depth of the color so it can be used by, well, me. It's useful for pixel artists working with old systems.

What the project does
PCP is a colorpicker that use a background to display different color plans from CIE Lab and LcH color spaces i.e. a/b, b/L, a/L, c/H, c/L, H/L. The third coordinate which is not in the plane define it in the colors volume. It can vary with slider as a constant or as a gradient. Upon these background you can use different tools i.e. segment, spline, polygon, related or palette to choose set of colors. Colors coordinates can be display in CIE Lab, CIE LcH, WEB, sRGB code. You can snapshot the whole user interface or just the color palette with coordinates as png file. You can also save in the clipboard the web codes.
Why the project is useful
The project is useful because standard colorpicker use colorspaces that are not adapted to the human vision of colors. They should not be used in graphic software to choose color scheme :
