I am trying to sample the color value of each channel in RGB from a pixel, is there any way to do this? Then I want to select the greater of the three and run a function that corrosponds with it. For instance if(red.value > green.value and blue.value) { red_run; }

Amm I didn't understand your point, could you tell me exactly what you want?
Do you want to obtain diferent colors you mean?

Try using a union like this:

union u_Color{  D3DCOLOR c;  struct  {    BYTE b;    BYTE g;    BYTE r;    BYTE a;  };};BYTE MaxColorComponent(D3DCOLOR c){  u_Color Color;  Color.c = c;  BYTE Max = Color.r;  if (Color.g > Max)    Max = Color.g;  if (Color.b > Max)    Max = Color.b;  return Max;}
