Boude Posted January 20, 2009 Share Posted January 20, 2009 I believe alpha mask takes the average of the mask's color and sets the original image's (the one that is displayed on your canvas) alpha to that average and does it pixel after pixel. Thats why color is not very important, also the alpha channel is only 1 channel red, green and blue are 3 so it would be impossible to use all 3 on the alpha channel.
