Gradient (Shade) This is the select gradient gadget. it is used to cause all the available tools to draw using a gradient and the colors designated in the palette and gradient requesters. Quite a few parameters modify how this function works. The palette requester uses the five color swatches as the gradient colors. The gradient select requester allows you to specify how many colors are used and their position. We highly recommend that you experiment with the different gradient tools so that you will become familiar with their operation.
