Whoever came up with such a hideous conglomerate of 80's neon colors?
They burn your eyes pretty much immediately

I faintly remember a WB 1.3 Palette setting called "High Contrast" or the like, that comes close, but not really.
Would it be possible to save a new set of "default" colors for the next release, preferrably those of the AmigaOS4 default?
