## About Golden Ratio and colours

### What is the Golden Ratio proportion?

The golden ratio, also known as the golden number, golden proportion, or the divine proportion, is a ratio between two numbers that equals approximately 1.618.

The Golden Ratio is applied in art, science and design for at least a few thousand years.

### What are Golden Ratio Colors?

Golden Ratio Colors are colors in the complete color spectrum that are defined by the Golden Ratio.

Every color on a screen is composed of values ranging from 0 to 255 of RGB (Red, Green, Blue). Every value is multiplied by 0,618. In total there are 1000 golden ratio colors. 64 of them are core colors that only use 0, 97, 158 and 255.

### Examples of

Golden Ratio colors

White has RGB values 255, 255, 255

Black has RGB values 0, 0, 0

255 x Golden Ratio = 158

158 x Golden Ratio = 97

Example 1: green is 0, 158, 97

Example 2: red is 255, 0, 0

Example 2: orange is 255, 158, 0

Example 3: grey is 97, 97, 97

## Math with RGB values and hex numbers

The hardest part, some math. The maximum value of 255 is multiplied by the Golden Ratio. For example: 255 x 0.618 = 157.59. The closest hex-value is 9E. 157.59 x 0.618 = 97.4. The closest hex-value is 61.
