To assign a color gradient to the color fill, click the arrow icon to expand the Area/Image color palette, and then do following:
1.In the color A list, select the starting color.
2.In the color B list, select the second color. If it's the same as the first color, then you have to specify the different tint. If you select [None] it will shade to no color.
3.In Fill, select Linear gradient.
4.In Angle, specify the angle of blending (0° is top down, 90° is left to right and so on).
5.Move the Speed slider on the right to give more space to the A color, or to the left, to give more space to the B color. The value of 50% distributes the color shading evenly.
6.Click the confirmation icon or press 8.
If you need to change the tint of the color, use the tint box to set a number between 0% (color behaves as "no color") and 100% (full color).
Figure 1: The A and B colors gets equal percentage of total space.
Figure 2: The A color gets 68% of total space, while the B color gets the remaining space.
Note
To assign transparent color (no color), select [None].
