Yellow or Green

["Electronicwaffle" <electronicwaffle@...>]

I thought about this soon after I made my Piecepack Applet. (see the 
files section) at the time, it was easier for me to go ahead and put 
in Red Blue Yellow and Green. This seems standard for most games,,, 
yet I can understand the reason posted for color blindness.Yellow on 
some woods could also be a "main" reason. However, US Playing Cards 
Makes a special Lo-vision  Bicycle playing card deck with the same 4 
colors (Red Black Green Blue) for each of their suits.    while I 
see the need for Color Blindness,  isnt there also a 
(version/strain?) of Color Blindness that is Red/Green??
