GrayLevel

GrayLevel[level]
is a graphics directive which specifies the gray-level intensity with which objects that follow should be displayed.

GrayLevel[g, a]
specifies opacity a.

MORE INFORMATION

The gray level must be a number between 0 and 1. »

0 represents black; 1 represents white.

On display devices with no native gray-level capability, dither patterns are typically used.

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

In GrayLevel[g, a], a is an "alpha channel" used to specify opacity.

GrayLevel[g, a] is equivalent to {GrayLevel[g], Opacity[a]}. »

If no opacity has been specified, GrayLevel[g] is equivalent to GrayLevel[g, 1].

Style[expr, GrayLevel[...]] specifies that expr should be displayed with the specified gray level. »
