I am surprised that there is such a thing as a “trend” in room decor

]]>I think part of the problem is our language. We really shouldn’t say that R+G=Y, we should say that the average of R and G is Y. That is, if you take the wavelength of red light (which predominantly stimulates a R cone) and the wavelength of G that mostly stimulates a G cone, add the two wavelengths and divide by two, you’d get a wavelength which stimulates the R and G cones about equally, which our brain then “interprets” as being yellow. Hope that helps.

]]>1- I was looking for the way to combine two waves with different wavelenghts to create a new wave with a predominating wavelenght (as a first fourier element) but i couldn´t. I wanted to add, for example, red + green, and get yellow. Mathematically. As a I saw, yellow has got a wavelenght in the optical range, around 575 nm. Is this possible at all? Or is it just a statistical mess that occur in our eyecones?

2- I have read in your post about extra-spectral colors. I was surprised, and of course helped me, because I was wondering how could we see white color, out of combining RGB, if white is not in the visible range. But how is it “harmonic” that two RGB secondary colors ARE in the range (yellow and cyan) but the other one isn´t (magenta)? How does this build-up of the cones work if not by adding-up waves?

Please please please help me somebody… my two small kids need their mum and my attention is not where it shouldbe….;).

Thanks in advance
