Working with the gradient

So far, the only adjustments we have made 

to the colors in our fractal have been through 

changes we have made to the coloring 

algorithm and its parameters. Since the 

coloring algorithm references colors found in 

the palette of the gradient, let s open and 

How gradients work

explore the Gradient Editor.

Select Gradient from the Fractal menu to bring up the gradient editor for our fractal.

You will notice that the colors in the gradient 

correspond to the colors in your image. Both 

the gradient editor and your fractal contain   

blue, white, yellow, red, and black areas.

Gradients

By clicking and dragging the horizontal slider on the Gradient editor to the right and left, you can 

rotate the gradient, and thus the colors in your image.

You can also move individual control points in 

the top 3 panels. Click on the top  and left 

most control point and drag it to the right.

Editing gradients

Notice that you can drag it horizontally past other control points and that doing so affects the 

shading between colors. Any changes made in the gradient editor are immediately reflected in your 

fractal onscreen.

If you drag a control point to a position immediately adjacent to another control point, this creates a 

sharp line between those two colors in the image rather than the smoother gradation that occurs 

when the control points are farther apart.
