Color perception






Neat.

534 is blue-green? I don't know... I don't think 420 is very blue either. And what was that nonsense about different colors having different temperatures?

I can't give you any scientific background to it but what I can say is that it's used to describe color casts in Photography as well as monitors... .
3,000K (K = Kelvins) is "warm" (lightbulb), 9,000K is "cold" (blue-ish cast). I like my monitor on the "cooler" side.
 
LOL something tells me you mean in blueish color, not temperature of your monitor. Although it might be interesting to watch what happens when you raise the temp of a monitor to 9000K :D Although I would seriously love to play with a laser powerful enough to do it :D

From Wikipedia:

"The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable hue to that light source. The temperature is conventionally stated in units of absolute temperature, kelvin(K)."
 
Hey ... heres a good question ;)

How do I know that when someone else looks at the colour "green" they don't see something else? Isn't it entirely possible that what I see as "green" someone else might see as "red"? How do I know that when someone looks at the world everything doesn't look completely different (colour wise). If that person had been living his/her whole life in that colour system then everything would seem normal to them, but strange to me.

Food for thought.

/offtopic.

Fascinating. I didn't realize that light color was measured in Kelvins Makes sense put that way. Hmm, makes me wish I had taken astronomy now, as that makes sense for star colors. Heh, learn something new every day. ty for the link.

I see. I've never really noticed.

Very fascinating. Though I am finding it quite ironic that "cooler" is warmer. :D

after searching a little on it, I'm actually surprised I've not caught on to this before. :oops:

Theres a lot of good reading there. The section on color blindness was interesting.

I remember some time ago my dad had a bright yellow truck that he ended up selling to
guy that could only see the color yellow, everything else appeared a different shade of
gray. He said it sure made finding his new truck in crowded parking lot a whole lot easier :D
