The color
data type represents a color in the sRGB color space. Each color channel is specified by an integer from 0 to 65535. An alpha channel may or may not be specified; if not, it is assumed to be 65535 (opaque).
The red
, green
, blue
, and alpha
properties are integer
s from 0 to 65535. The hue
, saturation
, and brightness
properties are number
s from 0 to 1.
The string
representation of a color
is the string
representations of the red, green, blue, and alpha components, in order, delimited by commas. If the color is opaque (the alpha component is 65535), only the red, green, and blue components appear in the string
representation.
The string
representation of a color
always includes a comma; it does not depend on the setting of the itemDelimiter
property.
OpenXION 1.0 and 1.1 did not support an alpha channel.
