Cerulean ( / səˈruːliən / ), also spelled caerulean, is a variety of the hue of blue that may range from a light azure blue to a more intense sky blue, and may be mixed as well with the hue of green. The first recorded use of cerulean as a colour name in English was in 1590. [ 1] The word is derived from the Latin word caeruleus, "dark blue ...
A monochrome[ 1] or monochromatic image, object or palette is composed of one color (or values of one color). [ 2] Images using only shades of grey are called grayscale (typically digital) or black-and-white (typically analog). In physics, monochromatic light refers to electromagnetic radiation that contains a narrow band of wavelengths, which ...
H: Normalized to [0–100] (hundred) Cyan ( / ˈsaɪ.ən, - æn /) [ 1][ 2][ 3] is the color between blue and green on the visible spectrum of light. [ 4][ 5] It is evoked by light with a predominant wavelength between 500 and 520 nm, between the wavelengths of green and blue. [ 6]

The human eye's red-to-green and blue-to-yellow values of each one-wavelength visible color [citation needed] Human color sensation is defined by the sensitivity curves (shown here normalized) of the three kinds of cone cells: respectively the short-, medium- and long-wavelength types.
Chromostereopsis. Blue–red contrast demonstrating depth perception effects. 3 Layers of depths "Rivers, Valleys & Mountains". Chromostereopsis is a visual illusion whereby the impression of depth is conveyed in two-dimensional color images, usually of red–blue or red–green colors, but can also be perceived with red–grey or blue–grey ...
The NCS coincides with the CMYK as regards the green-yellow-red segment of the color circle, but differs from it in seeing the saturated subtractive primary colors magenta and cyan as complex sensations of a "redblue" and a "greenblue" respectively and in seeing green, not as a secondary color mix of yellow and cyan, but as a unique hue. The ...
This enables the common blue to see color in the green part of the light spectrum extending up to 560 nm (2.2 × 10 −5 in). There is also a difference between the dorsal and ventral eye-shine of P. icarus , with the dorsal retina dominated by yellow-reflecting ommatidia and the ventral exhibiting yellow and red-reflecting ommatidia.
