RGB color patches

Description: this file has pure red, green, and blue color patches as well as combinations. It can be used for reflectance measurements. Results will vary based on your printer. You can also use them directly from your computer screen to show how each color is composed of varying amounts of red, green and blue light.

Color

This site explains what color is and its expression in light, etc...\r\nColor is a function of the human visual system, and is not an intrinsic property. Objects don't "have" color, they give off light that "appears" to be a color. Spectral power distributions exist in the physical world, but color exists only in the mind of the beholder.

Emission Spectrum Java Applet

This applet allows you to mix three colors of light (red, green, and blue) and see the resulting color of light. This is an example of additive color mixing and is representative of emission; it is not the same as mixing colored paints (an absorptive, or subtractive process).

Mantis Shrimp Eyes Might Inspire New High-Def Devices

Mantis shrimps are reef-dwelling marine crustaceans who trace their evolutionary lineage straight back to the Cambrian age 500 million years ago, before vertebrates had even evolved. They’re so biologically unique that biologists call them “shrimps from Mars.” They possess the animal kingdom’s most complicated eyes, capable of distinguishing between 100,000 colors — 10 times as many as humans — and seeing circular polarized light, or CPL, which can’t be detected by any other creature.
