Change portion of text color in matlab label

I know that it is possible to change the color of a label in a figure in matlab from the default black to another color. I have a need to change only part of the label text to a different color. For example.

h = xlabel('black, red');
set(h, 'Color',[1, 0 ,0])

This should change the entire text to red instead of black, but I'd only like to change the color of the word red.

Might have to look up Latex commands and embed Latex commands in the string. I don't know the Latex commands off the top of my head.
