Colors

Colors – Paint (Subtractive Color Model) Primaries: magenta, yellow, and cyan This color system is called subtractive because: each primary color absorbs (subtracts) a certain part of the color spectrum. every time a color is added, less light is reflected. When you mix all three primaries together, the entire spectrum of color is absorbed, and we’re left with black.

Colors - Lights (Additive Color System) Primaries: Red, Blue, Green Additive color systems start without light (black). Light sources combine to make a color. As colors are added, the resulting color is brighter.

Colors (colorpicker. com) We’ll be working with the additive color system Mix various amounts of red, green, and blue to create a color. Colors can be represented by rgb (red#, green#, blue#) Each color is indicated by a number from 0 -255 (0, 0, 0) = black (255, 255) = white
