Blue is the favorite color of all people. It’s nature’s color for water and sky, but is rarely found in fruits and vegetables. Today, blue is embraced as the color of heaven and authority, denim jeans and corporate logos. It is cold, wet, and slow as compared to red’s warmth, fire, and intensity.
Blue has more complex and contradictory meanings than any other color. These can be easily explained by pinpointing by the specific shade of blue.
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet.
