I guess this behaviour comes from old FoxPro times where complex coloring programming made - to simplify this programming. there are also other rules in the help file described (in addition to this rule - aking text always visible):

When using RGB values, the following rules determine the color:

When all three color values (R, G or B) are below 32, the color is black.
When all three color values (R, G or B) are between 32 and 64, the character code is dark gray.
When all three color values (R, G or B) are between 65 and 191, the character code is gray.
When any of the three color values (R, G or B) are above 191, the color is high intensity (+ or *).
