Key Differences
Cyan is one of the primary colors in the subtractive color model, used in color printing. It is a greenish-blue shade and is one of the four colors of ink used in color printing along with black, yellow, and magenta. Blue, on the other hand, is a primary color in the additive (RGB) color model used in digital displays and lighting. It is perceived when there is no green or red light contribution.
Cyan appears when blue light is mixed with green light at the same intensity in the RGB color model. It is also a secondary color in the RGB color model, formed by the combination of the primary colors blue and green. Blue is a spectral color. It is one of the seven colors of the rainbow and can have a range of shades, from the deep blues of the ocean to the pale blues of the sky.
The human eye perceives cyan as a bright, lively color often associated with water and the tropics. Cyan pigments are used to create the illusion of the blue sky in four-color printing. Blue is often associated with depth and stability, symbolizing trust, loyalty, wisdom, confidence, and intelligence. It is a dominant color perception in human vision.
In terms of ink and paint, cyan is a fundamental color that can be combined with magenta and yellow to create a full spectrum of shades in the CMYK color model. Blue is a traditional artistic color that can be lightened with white to create tints or darkened with black to create shades. Blue pigments are derived from a variety of compounds, including both natural and synthetic substances.
On computer screens, cyan is created by activating equal amounts of green and blue light at high intensity on a black screen. Blue is one of the three primary colors of light in the RGB color model and is a single wavelength color in the visible spectrum. Cyan ink is absorbed by red light, while blue pigments absorb red and green light.
