I'm referencing this for a webcam motion sensing experiment. If the total RGB values change by a certain amount, it's a great opportunity to capture an image and upload it to my site for future reference. Otherwise, it would save bandwidth and storage by not uploading like images. Best regards, Chris Thanks for sharing your experiment! I’m referencing this for a webcam motion sensing experiment.

switch (bitmap_bg.getPixel(x, y))
{
case 0x0000FF: b++; break;
case 0x00FF00: g++; break;
case 0xFF0000: r++; break;
default: other++; break;
}

You could also use some threshold to get less precision if exact red isn't realistic. Cool stuff, never thought of using something like this for a game. I can see it being useful for your latest ColorFill craze, lol.
