jaako, you need to read (and understand) the above article. You have some very basic misunderstandings about light. And particles and filters and chemistry and astronomy, and it is not the job of responders to you ATM (which would be better as a series of Q&A questions) to explain all of science and physics to you.
Hints: there is no "colorless" light; there is no "transparent" light; etcetera. You need to understand the theory and definitions before you make assertions about anything.
I'm not a hardnosed mainstreamer; I just like the observations, theories, predictions, and results to match.
