In 8bpp mode (256-colors) ALL PICTURES DOWNCOLORED by PaintCAD to 256 colors. Then fullcolored photo after opening in 8bpp will have less quality in comparison with it's original quality. Which method of downcoloring to 256 colors? You can select this method! =) There is TWO menu items in painting window: 'JoyRight'-'Adaptation' and 'JoyRight'-'Interpolation'.
