hi, i have a grayscale image loaded as gl_alpha:
1) where the image is black what is displayed is white
2) where the image is gray what is displayed is partially transparent
3) where the image is white what is displayed is fully transparent.
i'm wondering if the image that must be opaque (1) can be diaplyed with a different color instead of white

Change the drawing color before drawing the texture. (i.e. glColor*() or sprite.color in Cocos2D)
