Amiga understood the concept. Thus workbench was originally 4 color, which did stay as default. Conveiently, at the default hires (640x horiz resolution) 68k cpu would always be able to access chip ram, as the cpu is only able to use half the cycles, and at 4 color the blitter in Agnus uses most of the other half to stream bitplanes to Denise.
