• Secondary colors(additive synthesis)
• adding primary colors
• R G B black
• R G B blue
• R G B green
• R G B cyan
• R G B red
• R G B magenta

• Secondary colors(additive synthesis)
• weighted adding of primary colors
• 0.5 R 0.5 G 0.5 B grey
• 1.0 R 0.2 G 0.2 B brown
• 0.5 R 1.0 G 0.0 B lime
• 1.0 R 0.5 G 0.0 B orange

• Secondary colors(additive synthesis)
• compositing of primary colors

• Secondary colors(additive synthesis)
• compositing of primary colors

At normal viewing distances the eye does not
distinguish the dots, but blends or adds their
stimulus effects to obtain a composite color
effect.
