Shades of orange
In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel. The complementary color of orange is azure. Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light.

Varieties of the color orange may differ in hue, chroma (also called saturation, intensity, or colorfulness) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being an orange or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
Wrapping the spectrum into a color wheel
In a color proximity sense, a primary color has a color range of 120° (60° on each side of the color's hue) and any color has to be within that range to be considered a variation of that color. Secondary colors have a color range of 60° (30°), tertiary colors have a color range of 30° (15°), quaternary colors have a color range of 15° (7.5°), quinary colors have a color range of 7.5° (3.75°), and so on. Because orange is located at a hue angle of 30°, it has a tertiary color range of 15° and 45°, and any color out of this range is more related to yellow or red than orange. If the visible spectrum is wrapped to form a color wheel, orange appears midway between red and yellow:
