An ID2D1Brush, such as a color or gradient brush, can be set as a drawing effect if you are using the ID2D1RenderTarget::DrawTextLayout to draw text and that brush will be used to draw the specified range of text.

This drawing effect is associated with the specified range and will be passed back to the application by way of the callback when the range is drawn at drawing time.
