Question

I’m writing a tool to modify a game, and the game uses float’s to store RGB data (ranging from 0.0 -> 1.0). How would you best suggest I go about converting from float RGB Data to a Hex String/Byte RGB Data?

Answer 1

var rgbString = string.Format("#{0}{1}{2}", 
    ((int)(redValue * 255)).ToString("X2"), 
    ((int)(greenValue * 255)).ToString("X2"), 
    ((int)(blueValue * 255)).ToString("X2"));

edited (perhaps more readable code):

var rgbString = string.Format("#{0:X2}{1:X2}{2:X2}", 
    (int)(redValue * 255), 
    (int)(greenValue * 255), 
    (int)(blueValue * 255));
