Overlaying a colour over existing colour

Java 2D
#1

Hi, I’ve just been trying to think about how I’d do this but I’ve hit a brick wall. I have a pixel array containing the colours held at each pixel on the screen, but I’m trying to overlay a certain colour. I started by just looping through each pixel in the array and bitwise ANDing each colour by 0xFFFF0000 to give it a red tinge. However what I really need it to do is overlay a certain transparency of this colour, so ranging from a slight tinge to completely red with none of the original pixels showing. Does anyone know how I could achieve this?

Thanks,
Paul

Simply modify the value of alpha or the value of the red component.
