This causes colors that are set that are low numbered to be treated as themed colors -- basically honoring the palette of the terminal. The Style and Color implementations have changed quite a bit to permit growth -- the colors are now 64-bits wide to permit using the upper bits as flags, and to leave room for a future alpha channel. There is a new TrueColor() method on colors that obtains the value as strict RGB value, and this will be used in lieu of whatever terminal colors are provided -- giving the application full control over the color space if they want, without forcibly clobbering user preferences for terminals for the vast majority of cases. Indexed colors are created with the new PaletteColor API.
