7.17 Color-related Properties

color[top]

CSS2 Definition:

CSS2 Reference: [ "color" property ] http://www.w3.org/TR/REC-CSS2/colors.html#propdef-color

<color>

Any valid color specification.

This property describes the foreground color of an element's text content.

XSL modifications to the CSS definition:

XSL adds an "rgb-icc" function (see [expr-color-functions] ) as a valid value of this property.

color-profile-name[top]

XSL Definition:

<name>

Specifies the name of a color-profile for internal references.

rendering-intent[top]

XSL Definition:

"rendering-intent" permits the specification of a color-profile rendering-intent other than the default. "rendering-intent" is applicable primarily to color-profiles corresponding to CMYK color spaces. The different options cause different methods to be used for translating colors to the color gamut of the target rendering device.

Values have the following meanings:

auto

This is the default behavior. The User Agent determines the best intent based on the content type. For image content containing an embedded profile, it shall be assumed that the intent specified within the profile is the desired intent. Otherwise, the user agent shall use the current profile and force the intent, overriding any intent that might be stored in the profile itself.

perceptual

This method, often the preferred choice for images, preserves the relationship between colors. It attempts to maintain relative color values among the pixels as they are mapped to the target device gamut. Sometimes pixel values that were originally within the target device gamut are changed in order to avoid hue shifts and discontinuities and to preserve as much as possible the overall appearance of the scene.

relative-colorimetric

Leaves colors that fall inside the gamut unchanged. This method usually converts out of gamut colors to colors that have the same lightness but fall just inside the gamut.

saturation

Preserves the relative saturation (chroma) values of the original pixels. Out of gamut colors are converted to colors that have the same saturation but fall just inside the gamut.

absolute-colorimetric

Disables white point matching when converting colors. This option is generally not recommended.
