I am trying to use tksurfer to script overlay of a label + functional map onto an fsaverage5 surface.

In particular, I want to set the label to "fill" and color it red.

I have:

set labelstyle 0
labl_set_color 0 255 0 0

As you can see below, the output of label_print_list shows that the color of the label should be "255 0 0 " but it looks white in the output image.

Am I missing something?  Thanks
