A surface is white to the degree that it reflects the full spectrum of sunlight. If it's black, it absorbs all colors of the spectrum. So: why does a shiney black car make a better mirror than a shiney white car?

Colours in the natural are matt to the eye... Black cars are gloss!

"White" is not a color. It is simply the absence of dark.

Gee, Rapaire. You made me look it up.

"White is a color, the perception which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in nearly equal amounts and with high brightness compared to the surroundings."
Gunther Wyszecki and W. S. Stiles, Color Science, John Wiley & Sons.

He's wrong. That's black, or dark. The color sensitive cone cells in the eye actually react to dark, not light.

Froggy, what you are really seeing is the difference in perceived contrast of the reflected image. The greatest contrast, and the greatest detail, is from the black finish. Also differences in color would be more see-able because of the contrast. The colors and shadows of reflection are washed out by the amount of photons blowing back by all that nasty disfusey white paint.

I've always had a fondness for light eyes with dark hair. Light can be blue, green (favorite), hazel, etc.

OK, since Rapaire rejects the word of science, here are a few quotes on color-

Marc Chagall- "All colors are the friends of their neighbors and the lovers of their opposites."

Gilbert K. Chesterton- "White is not a mere absence of color; it is a shining and affirmative thing, as fierce as red, as definite as black. God paints in many colors, but he never paints so gorgeously, I had almost said so gaudily, as when he paints in white."

Pablo Picasso- Why do two colors, put one next to the other, sing? Can one really explain this" no. Just as one can never learn how to paint."

Becca said ...I've always had a fondness for light eyes with dark hair. Light can be blue, green (favorite), hazel, etc.

For me , it's the opposite.

I am a total pushover for blondes with dark brown eyes ...

( And they do exist, btw, natural blondes with dark brown eyes, cuffs and collars matching)

frogprince - to return to the original question about shiny black cars reflecting your face. The link "ask a scientist" gives an answer, but it is a bit over complicated sounding. A simpler desription would be :-
Paints (and things which act like paints - e.g. boot polish) are usually made from a coloured powder mixed in a "carrier" which is a clear liquid. Some paints dry because the carrier (e.g.water) evaporates, leaving the powder on the surface - this would give a matt finish. Other paints dry because the carrier changes chemically and remains part of the overall finish. In the case of your car paint (or lacquer)the carrier turns into a shiny clear coating with the paint powder embedded in it. The colour particles are surrounded by the clear finish.
The first thing light hits is the clear shiny finish, which acts like a sheet of glass would, reflecting your face. Any light that passes beyond the surface will then reach the embedded coloured "paint" particles.
If these are white, they will reflect light back through the outer glossy surface. The light you see will be the initial "mirror" reflection plus all the "white" reflected by the paint particles. RESULT - most of what you see is WHITE.
If the particles are black, light absorbing "paint" most of the light will be absorbed, so very little is reflected back at you. What you see is the "mirror" reflection, without extra reflected light behind it.

Hope that helps.
Quack!
Geoff.

Painting the pool black made for exception great contrasts in all the reflections. Even better it heats the pool a free 4 degrees.
