I've written a pascal version of some color controls which I've ported to

These controls includes a hue picker that has 2 styles (radial as shown and

have a color value slider edit box, where you can type out a R, G, B values
in bytes or floats, and it has a drop down with a left right slider that
shows you the colors.

They should be enough to create a decent pascal native color picker. Quick
example, adding the alpha picker and drop down edit is trivial:
