SUMMARY:Color: Physics and perception\, Chaos & Complex Systems Semina
r\, Pupa Gilbert\, UW Department of Physics
DESCRIPTION:Unless we are colorblind or are in the dark\, as soon as w
e look at any object\, we know what color the object is. Simple\, isnâ
€™t it? No\, not really. The color we see is rarely just determined by
the physical color\, that is\, the wavelength of visible light associ
ated with that color. Other factors\, such as the illuminating light\,
or the brightness surrounding a certain color\, affect our perception
of that color. Most striking\, and useful\, is understanding how the
retina and the brain work together to interpret the color we see\, and
how they can be fooled by additive color mixing\, which makes it poss
ible to have color screens and displays. I will show the physical orig
in of all these phenomena and give live demos as I explain how they wo
rk. Bring your own eyes!
