Blue is a primary color that can evoke many different feelings, impressions, and associations for people. Describing the color blue requires an understanding of its hue, shade, tone, and how it is perceived psychologically and symbolically. As a writing assistant, here is an attempt to comprehensively describe the color blue.
The Color Wheel
On the basic color wheel used by artists and designers, blue is one of the three primary colors along with red and yellow. In the RGB or additive color model, blue light mixed equally with red and green light produces white light. In the CMYK or subtractive color model used for printing inks, blue is one of the three primary colors mixed with yellow and magenta to produce black.
Blue sits opposite orange on the color wheel. These are considered complementary colors that create strong contrast when placed next to each other. Blue and orange are also analogous colors, meaning they share a common hue. The color wheel helps place blue in context among other colors and shows its relationship to them.
Properties of Blue
Blue wavelengths are some of the shortest visible wavelengths of light. The long wavelengths of red light vibrate slower and bend less than the shorter wavelengths of blue or violet light. This makes blue one of the most refracting colors, meaning it bends and scatters more as light passes through it. This explains why the sky appears blue as sunlight passes through the atmosphere and is scattered.
On the color spectrum, blue falls between green and violet. It is considered a cool color associated with tranquility, calmness, and passivity. In color psychology, blue evokes the feelings of trust, security, order, and conservatism.
