WHAT ARE THE LIGHT PRIMARY COLORS?
• The light primaries are: • – Red, which is scarlet. • – Green, which is the color of most leaves, and • – Blue, which is Newton’s indigo. • Overlapping beams of different colored light mix using these primaries. • Tiny nonoverlapping dots of color mix in this way. • All three colors are found in a Crayola (TM) box of 8 crayons. • Reflective glitter mixes like light. • The secondary colors of light are the pigment primaries. • Look at a color TV with a magnifier to see dots of light primaries. • A spinning disk with sectors of light primaries on it mixes in this way. • That toy top should have used the light primaries. • WHY DOES IT WORK? • The human eye has three kinds of light receptors. • The receptors are individually sensitive to the three light primaries: • The red receptor is sensitive to red, orange, and yellow. • The red receptor is somewhat sensitive to green and violet. • The green receptor is sensitive to yellow, green, and cyan. • The green receptor is somewhat sensitive
