Figure 13.33: The "Load Color From" submenu

Load Left [Right] Color From

These options give you a number of alternative ways of assigning colors to the endpoints. From the submenu you can

choose (assuming we’re dealing with the left endpoint):

Left Neighbor’s Right Endpoint This choice will cause the color of the right endpoint of the segment neighboring on

the left to be assigned to the left endpoint of the selected range.

Right Endpoint This choice will cause the color of the right endpoint of the selected range to be assigned to the left

endpoint.

FG/BG color These choice cause GIMP’s current foreground or background color, as shown in the Toolbox, to be assigned

to the endpoint.

RGBA slots At the bottom of the menu are 10 "memory slots". You can assign colors to them using the "Save" menu

option described below. If you choose one of the slots, the color in it will be assigned to the endpoint.

Save Left [Right] Color To These options cause the color of the endpoint in question to be assigned to the "memory slot"

selected from the submenu.

Figure 13.34: The Blending Function submenu

Blending Function for Segment/Selection

This option determines the course of the transition from one endpoint of the range (segment or selection) to the other, by

ﬁtting the speciﬁed type of function to the endpoints and midpoint of the range:

Linear Default option. Color varies linearly from one endpoint of the range to the other.

Curved Gradient varies more quickly on ends of the range than on its middle.

Sinusoidal The opposite of the curved type. Gradients varies more quickly on center of the range than on its ends.

Spherical (increasing) Gradient varies more quickly on the left of the range than on its right.

Spherical (decreasing) Gradient varies more quickly on the right than on the left.

Figure 13.35: The Coloring Type submenu

Coloring Type for Segment/Selection

This option gives you additional control of the type of transition from one endpoint to the other: as a line either in RGB

space or in HSV space.
