No. Every color counts separately. Only if all 32 bit are the same, then
it's the same color.

The central area uses the colors

clrMenuItemCurrentFg     = clrBlack
clrMenuItemCurrentBg     = clrYellow
clrMenuItemSelectable    = clrYellow
clrMenuItemNonSelectable = clrCyan
clrBackground            = clrGray50

which makes for a total of four different colors.
