Guess this might actually qualify as a physics question, but here goes!
On PF last year, I read a blurb that water, pool water specifically, looks blue because of the reflection of the blue sky. That sounded good to me, at the time...
I have a white tub, with white tile around it, just barely off-white walls and ceiling, incandescent lighting, taupe towels, light tan-ish vinyl flooring. Not a bit of blue anywhere. So why does the water in my tub look blue??
