Gradient steps

[csehz]

Hi, could you please have a short look on the attached picture, do you have maybe idea how to constraint the Fill tool to jump in certain color values at gradients?

Basically at Linear fill the Blend tool is great to execute this, so like on the left example can be seen just drawing two rectangles with RGB 0,0,0 and RGB 102,102,102 and the number of blend steps determine the between step color values.

But for the right side example so for Circular fill, does not have idea how to simulate the same, or maybe with Fill tool there is a way



thanks,
