<GradientName> is the preset name that must be between two quotation marks ("). The gradient is defined by set of color nodes (from 2 to 6) that must be specified one for each line in RGB format. Each color component must be in 0 to 255 range:

0    0    255

The #END keyword indicates the end of the gradient definition.
