Color defines a space. How we use this space depends on what our media can represent (consider the difference between our eyes and the monitor) and what we need it to express. Typically in computer graphics we first think of the RGB color space. This space is useful from an engineering point of view (we need red, green, and blue emitters to make a color pixel), however it can be very difficult to work with as human/artist. What other color spaces are there? How is the HSV color space different from RGB? Why might a human find this better to work with?
