OK, ColorData["Legacy", "Image"] returns a pretty picture now. (Useless,  
but pretty.)

ColorData["Legacy", "Panel"] is useable, but it might be better if it  
weren't in random order!!

ColorData["Legacy"]["PaleGreen"] works as advertised, and so does

Plot[Sin[x], {x, -Pi, Pi},
  Background -> ColorData["Legacy", "PaleGoldenrod"]]

The new features are very powerful, I admit.

The ColorSchemes palette is useless for accessing legacy colors, at my  
machine. Mouse settings and screen resolution MAY be a factor, admittedly,  
but paging down one screen at a time is a very ancient tradition for  
scroll bars, and I don't see why you would have abandoned it.

Yes, I know... this is a slider, not a scroll bar. But long lists need  
SCROLL BARS.
