Would someone be willing to make this plug-in for me? 15-bit color

That one would be easy. It would just be a script that rounds the current fg/bg colors to the nearest 5-bit equivalent (actually drops the 3 LSB's).
It could be assigned to a keyboards shortcut, and you would have to get used to strike that key after changing colors. But nothing would prevents Gimp from generating 24-bit colors (in a gradient, for instance).
