At the core of good science and engineering is the careful and respectful treatment of data. We calibrate our instruments, scrutinize the algorithms we use to process the data, and study the behavior of the models we use to interpret the data or simulate the phenomena we may be observing. Surprisingly, this careful treatment of data often breaks down when we visualize our data.
It has been known for some time that colors can be described by three numbers. If I show you light of a certain color and ask you to match it by combining lights of three other colors and varying their intensities, you'll typically be able to find a combination that looks indistinguishable. But the wavelengths you combine might be very different from the wavelengths I showed you. Light of the wavelength corresponding to yellow and light of the right combination of red and green wavelengths will look the same, even though they are physically quite different.[more inside]

It's just another clever colour matching game. It seems to be getting trickier and trickier, but don't let that confuse you - it's all about matching the colours perfectly.
ColorJack is a color designer sandbox that takes Color Scheme Designer (previously) several steps beyond. It has the standard color wheel, and outputs to web, PhotoShop, and Illustrator, with the ability to "see" those same hues under various conditions of color blindness... and then you get truly creative areas, like the Color Piano and Color Galaxy.

Plenty of Colour is a site devoted to colour inspiration: not only from shades (black, red, pink, and purple to start), but also colourful places and spaces and objects of desire. There's also ColourLovers, (mentioned many times previously on the blue), with the The Colors of Good vs. Evil.
