COLORS

Used in:	GOPTIONS statement; GDEVICE procedure; GDEVICE Gcolors window
Default:	device dependent

colors-list

specifies one or more SAS color names. If you specify more than one color, separate each name with a blank. See SAS/GRAPH Colors for information on specifying colors and using a colors list.

To change some of the colors in the colors list and retain others, you can use a null value for colors you do not want to change. For example, to change COLORS=(RED GREEN BLUE) to COLORS=(WHITE GREEN BROWN), you can specify COLORS=(WHITE,,BROWN).

NONE

tells SAS/GRAPH to use only the colors that you explicitly specify in program statements and to ignore the device's default colors list.

Note:   If you specify COLORS=(NONE) and omit a color specification for a graphics element, such as patterns, SAS/GRAPH selects at random one of the colors already specified in your program.

Example 3. Rotating Plot Symbols through the Colors List

Details

• The order of the colors in the list is important when you use default colors. For example, the colors used for titles, axes, and surfaces in the G3D procedure are assigned by default according to their position in the colors list.

• If you omit or reset COLORS=, SAS/GRAPH uses the default colors list for the current device. To explicitly reset the colors list to the device default, specify either

  goptions colors=;
  goptions colors=();

• If you use default patterns with a colors list specified by COLORS=, the patterns rotate through every color in the list. If the colors list contains only one color, for example COLORS=(BLUE), the solid pattern is skipped and the patterns rotate through only the appropriate default hatch patterns for the graph.

  Note:   By default, if black is the first color in a device's colors list, default pattern rotation skips black as a pattern color, but uses black as the area-outline color. Thus, the outline color is never the same as an area's fill color. Using COLORS= to change the colors list changes this default pattern behavior. When COLORS= is used, all colors in the specified colors list are used in color rotation, and the outline color is the first color in the specified colors list. Thus, the outline color will match any area using the first color as its fill.  
  

  See PATTERN Statement for more information on pattern rotation.
