Hue

Hue[h]
is a graphics directive which specifies that objects which follow are to be displayed, if possible, in a color corresponding to hue h.

Hue[h, s, b]
specifies colors in terms of hue, saturation and brightness.

Hue[h, s, b, a]
specifies opacity a.

MORE INFORMATION

The parameters h, s, b and a must all be between 0 and 1. Values of s, b and a outside this range are clipped. Values of h outside this range are treated cyclically. »

As h varies from 0 to 1, the color corresponding to Hue[h] runs through red, yellow, green, cyan, blue, magenta, and back to red again. »

Hue[h] is equivalent to Hue[h, 1, 1]. »

The alternative forms Hue[{h, s, b}] and Hue[{h, s, b, a}] can also be used. »

On monochrome output devices, a gray level based on the brightness value is used.

For 3D surfaces, explicit Hue directives define surface colors; the final shading depends on lighting.

Glow[Hue[...]] specifies color independent of lighting. »

In Hue[h, s, b, a], a is an "alpha channel" used to specify opacity.

Hue[h, s, b, a] is equivalent to {Hue[h, s, b], Opacity[a]}. »

If no opacity has been specified, Hue[h, s, b] is equivalent to Hue[h, s, b, 1].

Style[expr, Hue[...]] specifies that expr should be displayed with the specified color. »

Use diffuse and specular surface color:

Use glow color, setting the diffuse surface color to black:

Use Blend to mix two or more colors:

Use Lighter and Darker to mix with white and black respectively:

Generalizations & Extensions (3)

Hue[h] is equivalent to Hue[h, 1, 1]:

Hue[{h, s, b}] is equivalent to Hue[h, s, b]:

Use Opacity with Hue:

Use the opacity argument in Hue directly:

Applications (3)

Select

complementary colors, by selecting them maximally apart on the color wheel:

Color the filling according to the argument of a complex function:

Color the surface according to the argument of a complex function:

Properties & Relations (1)

The hue value is cyclic with period 1:

Saturation determines how vivid the color is:

Brightness determines the brightness of the color:

A portion of HSB color space with maximal brightness:

Possible Issues (1)

Saturation and brightness values outside of the 0, 1 range will be clipped:

In plot functions, use ColorFunctionScaling to control global scaling of variables:
