I was more mulling on RGB() creating grey tones and if different red/green saturations make a difference to Lutz...
interesting: Canadian site prefers gray to grey...

>Just to be true to my word, I never bought a gray car. Went burgundy, blue, dark ink blue, sky blue. Because nothing decent was offered in cyan, turquoise or violet.

yellow, gold met, white, light blue met, ocean blue met, red, grey met, burgundy met, silver met, hunting green met...
with the silver met taking 2nd & grey met 3rd place in time of usage
but as I never bought a new car, colour was never chosen and also never deciding,

From POV on beauty I prefer darker colour metallics, but in summer you pay in sweat.
Benefit today: I can shut up environmentalists until they actually see my car ;-)

gold met was hit by stupid other drivers 3 times (front, left& back) in 8 month period,
then received a stone in right door still left pristine via demonstration patron...
ocean met had sound system stolen twice (but only via smashed windows)
red and burgundy met totaled by other driver stupidity -
green met was scratched front to back on side with sharp object (one of ~40 cars in same street)

Visibility did not help in my cases, although in last case probably did not matter ;-)
