Right-click the WordArt object & select Format Text Effects. Choose
Text Fill from the list, click the
Gradient button, select a gradient Style [probably
Radial] then design your own Rainbow gradient. If you choose Linear don't overlook the Angle settings. You can also move the dialog out of the way & observe how your settings actually look.
