Week 1 introduction to the light
This document provides an introduction to light and color design theory. It begins by defining electromagnetic waves, including that they can be reflected, refracted, emitted or absorbed by matter. It then discusses the electromagnetic spectrum and different types of electromagnetic waves such as radio waves, microwaves, infrared, light, ultraviolet, x-rays and gamma rays. It focuses on light and the visible spectrum, which consists of the colors red, orange, yellow, green, blue, indigo and violet. It introduces color design theory and the concept of using color to express emotions. It explains that color wheels are used to show the relationships between colors and are made up of primary, secondary and tertiary colors.

- 12. THE COLOR WHEEL •The color wheel is a chart of colors of the visible spectrum that is used to show how colors relate to each other.
- 13. • The colourwheel is at the centre of colour theory and is a simple means of showing the relationships between colours. Usually, colours on the right side of the wheel are warm whereas those on the left are cool.
- 14. THE COLOR WHEELIS MADE UP OF : 1.three primary colors, 2.three secondary colors, and 3.six tertiary colors.
- 15. PRIMARY COLORS • Thereare just three primary colours: red, yellow and blue. Primary colours cannot be made or mixed from other colours; they are the essentials from which all other colours are made.
- 16. SECONDARY COLORS • Mixingeach of the primary colours with its neighbour in equal amounts produces the three secondary colours: green, orange and purple.
- 17. TERTIARY COLORS • Mixinga primary colour and a secondary colour (in a ratio of 2:1) produces a tertiary colour. These tertiary colours are usually given a two word name, such as blue-green, yellow-green, red-purple, blue- purple, red orange and yellow-orange. • Ratio means proportion; so a ratio of 2:1 means two measures of one colour and one measure of the other. For example: blue, blue and green gives blue-green, yellow, yellow and green gives yellow-green.
