Choosing colors is a careful business, and not just when it comes to paint.

Youve probably seen it in school, but heres a quick refresher just in case youve forgotten.

Red, blue, and yellow are primary colors.

Orange, green and violet are hence called secondary colors.

Tertiary colors like red-violet and blue-violet are derived by mixing a primary color with a secondary color.

All colors have tints and shades.

The harmonious color combinations are called color schemes sometimes the term color harmonies is also used.

Color schemes remain harmonious regardless of the rotation angle.

Each has its own purpose to convey emotions.

And theyre actually pretty simple.

Complementary colorsare any two colors opposite each other on the wheel.

For example, blue and orange, or red and green.

These create a high contrast, so use them when you want something to stand out.

Ideally, use one color as background and the other as accents.

Split complementary colorsuse three colors.

The scheme takes one color and matches it with the two colors adjacent to its complementary color.

For example, blue, yellow-orange and red-orange.

This scheme is ideal for beginners because it is difficult to mess up.

Analogous colorsare any three colors next to each other on the wheel.

For example, orange, yellow-orange, and yellow.

With analogous colors, its best to avoid hues as they can be jarring.

Instead, focus on tints of analogous colors.

Another tipColor Wheel Pro sharesis to avoid combining warm and cool colors in this scheme.

Triadic colorsare any three colors that are equally apart on the color wheel.

For example, red, yellow and blue.

The Triadic scheme is also high-contrast, but more balanced than complementary colors.

Tetradic or double complementary colorsuses four colors together, in the form of two sets of complementary colors.

For example, blue and orange is paired with yellow and violet.

Avoid using pure colors in equal amounts.

And this goes on till you get pure white or pure black.

Apart from tints and shades, there are also tones, which is mixing the hue with grey.

Using saturation and tint/shade variations of a color is always good.

Using it with pure white or black can be efficient, though.

A scheme like this can be efficient, but it can very easily look boring.

Using an achromatic scheme with just one bright color for highlight can be very effectful.
