The OSD color palette registers store four sets of Y, Cb, Cr values. Color0 = {Y0, Cb0, Cr0} is for
lyric guide only. Color1 ~ color3 are used to control the colors of display characters. For example, if
the color index of one character is 2, then its color component {Y, Cb, Cr} = {Y2, Cb2, Cr2}. Any
characters with color index 0 will not be shown in screen (turn-off state).
