Mixing two colours: how the midpoint is found
Mixing paint and mixing light behave differently, but screen colours follow a simple channel blend. This guide explains the maths.
What is the Color Mixer?
Choose two colours and a mix percentage, and this tool blends their red, green and blue channels in that proportion. A 50/50 mix gives the exact midpoint; moving the slider toward one colour shifts the result toward it.
How to use it
- Enter two hex colours.
- Set the share of the first colour.
- Read the mixed hex and RGB values.
Worked example
Red and blue at 50/50 mix to #800080, a balanced purple.
How do you mix red and blue?
Average each channel: half of red plus half of blue gives purple, because red and blue stay full while green stays at zero.
Frequently asked questions
What does 50% mean here?
It means half of each colour, giving the exact midpoint between them.
Is mixing done in RGB?
