Three nodes: Overlay, add, and screen. All for color. Because the default blend node separates each channel, and so it will only ever approach pure color—never white. These are three combinations of blends that mix every channel. Great for making a glow effect.

Thank you for telling me. Something definitely seems wrong. The nodes are fairly old by now, so it's no surprise they broke. I'll look into it and post an update if I can get it to work.

I really like the idea behind this, but the nodes don't seem to work as expected.
Maybe an update broke them somehow, because 1 of the 2 input colors just turns white for add and overlay. And the top input is missing altogether for screen. Also, some colors get very blown out.
