Mom, why's the sky blue? I asked about two.
God made it that way, I heard her say with no fuss on city bus.
Mom's why's that lady black, hushhhhh she and other eyes shot back.......

Physics without psychophysics seemed as empty as biology without chemistry.

Seriously color has always facinated me and coincidentally rainbows facinated my daughter about the time I was mapping infrared color bands to the optimum visible. I had to dig deeper before Google or expressed interest in nonspectral magenta.

How come magenta violates closure?
It falls out of the set of visible spectrum yet it maximizes our chroma discrimination (see Judd & Mac Adam ellipses) and it taught me when we say we sense temperature we actually sense IR color ratios (by wireless remote cell-cell biophysics resonance). Mapping colors for the blind with dots of heat is bit tougher challenge, but not far off.
Now my grand daughter is facinated by rainbows in nature and artificial ones dispersed by glass, diffracted by CDs etc.

Best answer? I guess the wonders of science were trumped by my wonder wife who majored in art and psychology!!! A thing of beauty is joy forever, but news and hues of Nobel Prize last a day or two.
