A gradient is a smooth blend of two or more colors. Flash applies excellent gradients that can be used to give graphics a three- dimensional appearance. The speaker graphic used in the 20k example uses two gradients: one for the inner and one for the outer cones. Flash offers complete gradient editing control and you can use that control to build both concave- and convex-appearing objects.
Before you can apply the gradients, you must first create the speaker outline that will hold the gradients.
The resulting graphic should resemble the speaker outline shown in figure 03:15.
