# 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. Huespecifies colors in terms of hue, saturation, and brightness. Huespecifies opacity a.
• The parameters h, s, b, and a must all be between and . Values of s, b, and a outside this range are clipped. Values of h outside this range are treated cyclically. »
• As h varies from to , the color corresponding to Hue[h] runs through red, yellow, green, cyan, blue, magenta, and back to red again. »
• The alternative forms Hue and Hue 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 specifies color independent of lighting. »
• In Hue, a is an "alpha channel" used to specify opacity.
• If no opacity has been specified, Hue is equivalent to Hue.
• Style specifies that expr should be displayed with the specified color. »

 Scope   (2)
Use diffuse surface 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:
Hue[h] is equivalent to Hue:
Hue is equivalent to Hue:
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:
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:
Saturation and brightness values outside of the 0, 1 range will be clipped:
In plot functions, use ColorFunctionScaling to control global scaling of variables:
Visualizing the HSB color space:
Dynamically view the color planes in the brightness direction:
