Monochromatic, Complementary, Triadic, and Square are colour schemes, also known as style and appeal.

Monochromatic:

• Uses 1 colour (its tint, tone, shades).

• Boring and bland

Complementary:

• Matches colours opposite each other in the colour wheel.
• Uses both warm and cool.
• Provides contrast.

• Useful if temperature needs to dominate.

Warm colours are seen as positive and energetic.

Red means danger or anger.

Cool colours mean relaxing or reserved.

Green means greed or envy.
