How do I change the color of a subformula?

You can use the color command as follows:

• color red ABC typesets ABC.

There are eight different colors to choose from:

• white, black, cyan, magenta, red, blue, green, yellow.

You can apply a color to an entire subformula if you group it with { } or other brackets. Example:

• Enter A B color green {C D} E to typeset ABCDE.

When several colors are applied, the innermost takes precedence as shown in this example:

• Enter color blue {A B color yellow C D} to get

ABCD.

You cannot select the background color; a Math formula is always transparent. This means that it inherits the background color from the document (for example a writer document) it is contained in.
