Shades of gray
Shades of gray, also known as variations of gray, covers gray in perception and colorimetry: humans distinguish about 1,000 shades, while 8-bit displays encode 256 levels.
Shades of green
Shades of green, also called variations of green, are the colors between yellow and cyan in the visible spectrum, produced in nature chiefly by chlorophyll.
Shades of orange
Shades of orange, also known as Variations of Orange, are the named variants of the color orange, the hue between red and yellow, spanning roughly 575 to 595 nm.
Shades of purple
Shades of purple, or variations of purple, are the family of colors between blue and red, including violet, lavender, lilac, and mauve; purple is nonspectral.
Shades of red
Shades of red, also called a list of shades of red, range from pale pink through scarlet and crimson to dark maroon, with red light spanning 620 to 750 nm.
Shades of violet
Shades of violet are the colors at the short-wavelength end of the visible spectrum, around 380–420 nm, distinct from purple, a mixture of red and blue.
Sky blue
Sky blue, known in Japanese as sora-iro, is the color of the daytime sky, produced when Rayleigh scattering by air molecules sends blue light to the eye.
Spectral color
Spectral color: the color of monochromatic light, one wavelength of the visible spectrum. Newton's seven-color spectrum (originally five), Newton's color circle, and nonspectral colors like purple and magenta.
White
White is the color perception produced by light containing a broad, balanced mixture of wavelengths; many different spectra, from tungsten lamps to LEDs, look white.
Yellow
Yellow, also called the color yellow, is perceived by light of about 577 to 597 nanometers, between green and orange, and is a subtractive primary color of printing.
