For Goethe, "the highest is to understand that all fact is really theory. The blue of the sky reveals to us the basic law of color. Search nothing beyond the phenomena, they themselves are the theory." [18] [Goethe] delivered in full measure what was promised by the title of his excellent work: Data for a Theory of Color.
In the CMYK color model, the primary colors magenta, cyan, and yellow together make black, and the complementary pairs are magenta–green, yellow–blue, and cyan–red. Color printing, like painting, also uses subtractive colors, but the complementary colors are different from those used in painting.
Cyan is any of the colors in the blue-green range of the visible spectrum, i.e., between approximately 490 and 520 nm. It is considered one of the main subtractive primary colors. Cyan is sometimes considered green or blue because of the way it appears.
This is the issue of color rendition, quite separate from color temperature. An orange or cyan object could appear with the wrong color and much darker as the LED or phosphor does not emit the wavelength it reflects. The best color rendition LEDs use a mix of phosphors, resulting in less efficiency and better color rendering. [citation needed]
CcMmYK, sometimes referred to as CMYKLcLm or CMYKcm, is a six-color printing process used in some inkjet printers optimized for photo printing. [1] It complements the more common four color CMYK process, which stands for Cyan, Magenta, Yellow and Key (black), by adding light cyan and light magenta. Individually, light cyan is often abbreviated ...
Evidence indicates that what Newton meant by "indigo" and "blue" does not correspond to the modern meanings of those color words. Comparing Newton's observation of prismatic colors with a color image of the visible light spectrum shows that "indigo" corresponds to what is today called blue, whereas his "blue" corresponds to cyan.

They are popular in aviculture because of their striking color, ability to talk, ready availability in the marketplace, and close bonding to humans. It is the most commonly kept macaw species in captivity worldwide as a pet or companion parrot and is also the cheapest among the large macaws.
Spectral colors (colors that are produced by a narrow band of wavelengths) such as red, orange, yellow, green, cyan, blue, and violet can be found in this range. These spectral colors do not refer to a single wavelength, but rather to a set of wavelengths: red, 625–740 nm; orange, 590–625 nm; yellow, 565–590 nm; green, 500–565 nm; cyan ...
