Re: GDP: Colors in RGB?

[Erlend Aasland]

Hi Trevor,

Yes, the internal color format is hidden from the user on purpose. The  
reason for this is that if we need to change the internal format  
sometime in the future, the format change will not be noticed by the  
user. With the default color macros and the X11 color macros, the user  
won't have to care about the internal color representation.


Kind regards,
  Erlend Aasland
