What are blues colors?

Blues colors refer to shades of the color blue. The color blue is one of the primary colors in traditional color theory, along with red and yellow. Blues play an important role in art, fashion, and decor due to their calming yet melancholic emotional associations. In this article, we will explore what defines blues colors, look at common shades of blue, examine the psychology and meaning behind different blues, and provide examples of how blues are used in design.

Defining Blues Colors

The color blue sits between green and violet on the visible spectrum of light. It has a wavelength of between 450 and 495 nanometers. Blues contain traces of the color red to give them depth and vibrancy but lean more heavily towards the cooler, calmer colors.

Blue is considered one of the three additive primary colors, along with red and green. This means that mixtures of blue light can create other colors on the visible spectrum. For example, mixing blue and green light makes cyan, while mixing blue and red makes magenta.

In the RYB or traditional artist’s color wheel, blue is considered one of the three primary colors, along with red and yellow. When artists mix blue paint with red or yellow paint, they can create secondary colors like violet and green.

So how are blues defined compared to other shades of blue? Generally, blues refer to deeper, darker shades of blue that have more red or purple traces mixed in. Lighter blues like azure or baby blue are not considered true blues.
