They all represent numbers with some special characteristics.Ī Normalized is a number between 0 and 1.Īn UnsignedByte is an integer between 0 and 255.Īn Angle is unrestricted in value but there are several operations that only make sense on angles (sine, cosine, and so on) and several representations (angles, radians) in common use. These methods use types - Angle, Normalized, and UnsignedByte - that have not seen before. rgb ( red : UnsignedByte, green : UnsignedByte, blue : UnsignedByte ) hsl ( hue : Angle, saturation : Normalized, lightness : Normalized )Ĭolor. There are two main methods to create colours: Color. We need to know how to create and manipulate colors. The strip of colors below shows the effect of varying saturation from 0.0 to 1.0,įor fixed hue (170 degrees) and lightness (0.5).Ĭhanging saturation goes from a dull gray to a bright and vibrant color. If we arrange colors in the familiar color wheel,ĭistance from the center corresponds to lightnessĪnd steps around the outside correspond to changes in hue: as hue, saturation, and lightness (HSL).īetter corresponds to our perception of color.as triples containing red, green, and blue values (RGB) or.In Doodle we can represent a color in one of two ways: To create programs that can automatically construct attractive color palettes. In this exercise we will explore the creation of color palettes.Īn attractive picture must make good choices for color.Ĭolor theory has developed to explain combinations of color that go together.
