Using SVG for additive color mixing (additive blending)

I am looking out to find a way to create an interactive illustration of additive colors as shown in this image:

color wheel

The red, blue and green areas should be »draggable« but since I am not that familiar with such kind of color processing I the only idea that came into my mind was the use of a blend-mode filter for each of the elements. The <feBlend> filter does not support »additive«, but there are also the <feColorMatrix> and <feConvolveMatrix> filters which seem to offer a wide range of possible color transformations.

Is it possible to create an additive blend-mode with these filters? I would appreciate links to any additional kind of resource/tutorial where I could get more Information about how these filters work!

Greetings...

  • thanks for this, seems to answer my question... Perhaps I should have added this to my question: Are there solutions that work in all major browsers (ff, opera, safari, chrome)? – philipp Jan 16 '13 at 16:46
  • philipp - the second answer to that question has my solution - which is cross-browser – Michael Mullany Jan 16 '13 at 18:21
