What glyph are you using to display the HSPs (i.e., what value are you
passing as the 'glyph' when you call add_track on the objects that
represent the HSPs)? If you're currently using the 'graded_segments'
glyph, try changing it to a plain old 'segments' glyph and see what
happens; the former sets the intensity of the color based on the
features' scores, while the latter does not.
