How can I change the color of a single word in my Simple Theme header?

In Simple Theme:

Trying to be able to Color one large Word in my Header>tagline>text [BOX] a different color than default Black.

The Box has no provisions at top for any Color changes, although you can change paragraph, bold, italic, etc.

Can anyone (expert?) help me with this coding OR? Thanks very much!
