> What I mean by that is that color always clamps to 1.0, so if you give oversaturated colors (1.0 when alpha is 0.5, for instance), and blending results in a color greater than 1.0, the result is clamped to 1.0. I believe that is what the HTML compositor specifies and that's what WebKit does when compositing. I think Firefox is doing something different. But I'll wait for Vlad to chime in...

Just for clarification how can you get out of range pre-multiplied
values into HTML without WebGL?
