What's going on with Rhodamine B? Its color doesn't change as a function of concentration? Why does its transmittance data seem to bounce back and forth between 0 and 1?
Dang, I want those interactive plots with IPython notebooks
C.R.E.A.M. - CIE Rules Everything Around Me
So many factors go into color matching and this is just the tip of the iceberg. Pigments vs dyes, solutions vs solid substrates, angles, light sources, observers...etc. Color is subjective, so creating an objective color-output that matches an average person's perceptual color vision is one hell of a fascinating, and expensive puzzle.
Are Google analytics usually in Julia notebooks?
My Mom would love this! She's a Chemistry teacher. Would definitely share it with her..
λ->planck(λ*nm,T=T)*m^3/Watt*cie_color_match(λ)
Even if you don't follow the first half, it's worth skimming to get to the bottom where the computations predict the colors of chemical compounds with remarkable accuracy. The "Copper (II) aqua ion" one is the most impressive to me – the entire color spectrum is spot on.
