<color>
The uniform color of the background.
In MathML 3 and earlier versions, a more limited set of values was supported. Since MathML Core, the syntax matches CSS <color> values.
This attribute was designed for MathML applications that are not CSS-aware. Since MathML Core, the use of equivalent CSS is recommended instead.
