CSSPrimitiveValue: getRGBColorValue() method

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The getRGBColorValue() method of the CSSPrimitiveValue interface is used to get an RGB color value. If this CSS value doesn't contain a RGB color value, a DOMException is raised. Modification to the corresponding style property can be achieved using the RGBColor interface.

Note: This method was part of an attempt to create a typed CSS Object Model. This attempt has been abandoned, and most browsers do not implement it.

To achieve your purpose, you can use:

Syntax

js

getRGBColorValue()

Parameters

None.

Return value

An RGBColor object representing the color value.

Exceptions

Type Description
DOMException An INVALID_ACCESS_ERR is raised if the attached property can't return an RGB color value (i.e. this is not CSS_RGBCOLOR).

Examples

js

const cs = window.getComputedStyle(document.body);
const cssValue = cs.getPropertyCSSValue("color");
console.log(cssValue.getRGBColorValue());

Specifications

This feature was originally defined in the DOM Style Level 2 specification, but has been dropped from any standardization effort since then.

It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
