INTRODUCTION TO THE LIGHT
WHAT ARE ELECTROMAGNETIC WAVES ?
• If you have ever tuned in to listen to a radio, spoken on a handphone, turned on a light, had an X-ray taken, felt the warmth of sun on your skin.
• You have experienced electromagnetic wave
• can all be reflected or refracted
• can all be emitted or absorbed by matter.

LIGHT
• Visible light is the part of the Electromagnetic spectrum which can be detected by the human eye.
• The visible light has its own spectrum which consist of the 7 colours of light :
RED ORANGE YELLOWYELLOW GREEN BLUE INDIGO
VIOLET
COLOR DESIGN THEORY
“Color is not given to us in order that we should imitate nature. It was
given to us so that we can express our own emotions,”
Henri Matisse
SPECTRUM
• All color is contained within white light. When light passes through a crystal prism it is dispersed into the spectrum range of visible colors.
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.
• The colour wheel 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.
THE COLOR WHEEL IS MADE UP OF :
1.three primary colors, 2.three secondary
colors, and 3.six tertiary colors.
PRIMARY COLORS
• There are 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.
SECONDARY COLORS
• Mixing each of the primary colours with its neighbour in equal amounts produces the three secondary colours: green, orange and purple.
TERTIARY COLORS
• Mixing a 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.
