The analogous colours scheme can be achieved using contiguous colors within the chromatic circle. In the monochromatic combination we chose different shades within the same color. In the case of the analogous combination we will create a soft contrast by extending slightly the chromatic variety. We will choose a primary colour and their tertiary adjacents from the chromatic wheel.
For example, we can opt for a combination of yellow, yellow-orange and lime green.
Applied to a bedroom, it would give us this result:
This combination is also known as harmonic colour combination.
Here is another example, in this case with red, red-orange and yellow-orange. The carpet is the element that determines this kitchen decor, getting all the attention.
