Color Picker for 64k colors in this format

[PickyBiker]

I need a program or the code to pick 64k and 256 colors using the following formats:

RRRR RGGG GGGB BBBB for 64k COLORS

and

0000 0000 RRRG GGBB FOR 256 COLORS

Anyone got something? Even a formula to get these from a standard color format would help.

All I see in that is the RGB values. I need the 565 values as shown in the op.
