A hue refers to the gradation of color within the visible spectrum, or optical spectrum, of light. "Hue" may also refer to a particular color within this spectrum, as defined by its dominant wavelength, or the central tendency of its combined wavelengths. For example, a light wave with a central tendency within 565-590 nm will be yellow.

In painting color theory, a hue refers to a pure color —one without added white (tint) or black (shade) pigment.

In an RGB color space, hue can be thought of as an angle φ in standard position. To calculate φ, let R, G, B be the color coordinates in RGB space, defined on a scale from zero to one. Then, after obtaining the brightness μ and the saturation σ, the hue could be obtained from

$\backslash phi\; =\; \backslash arccos\; \backslash left(\; \{R\; -\; \backslash mu\; \backslash over\; \backslash sigma\; \backslash sqrt\{2\}\}\; \backslash right)$

(Compare with standard score). Using this formula, φ = 0° href="http://articles.gourt.com/en/Radian">^c would corresponds to red, while φ = 120° would correspond to blue, and φ = 240° [4π/3^c would correspond to green.

Hue feels a lot less stressful than Saigon. More charming than Saigon I find

Wow, Hue is so different from Saigon. Much greener a lot of trees in the city, more shadows and a lot less crowded buildings
