Color Names

Share:

Description

Returns the built-in color names which R knows about.

Usage

1
2
colors (distinct = FALSE)
colours(distinct = FALSE)

Arguments

distinct

logical indicating if the colors returned should all be distinct; e.g., "snow" and "snow1" are effectively the same point in the (0:255)^3 RGB space.

Details

These color names can be used with a col= specification in graphics functions.

An even wider variety of colors can be created with primitives rgb, hsv and hcl, or the derived rainbow, heat.colors, etc.

Value

A character vector containing all the built-in color names.

See Also

palette for setting the ‘palette’ of colors for par(col=<num>); rgb, hsv, hcl, gray; rainbow for a nice example; and heat.colors, topo.colors for images.

col2rgb for translating to RGB numbers and extended examples.
