And you can force PaintCAD to search TWO colors nearest to original color, and mix it in proportions. It is 'JoyRight'-'Adaptation'-'Super'. SUMMARY (IMPORTANT): in 8bpp mode before opening ??? or ???(Clipboard) you NEED TO SET 'JoyRight'-'Interpolation'-'Hyper-palette' OR 'JoyRight'-'Interpolation'-'UNI-palette' (and then select Adaptation, if you select uni-palette). I recommend you to select 'UNI-palette' and any adaptation. By default there is 'Simple' adaptation and 'UNI-palette' interpolation.
