ok, I think I figured it out. I just needed to explicitly define the color of the plot (color_line). I've never needed to do this before, but it worked!

The annotations are all still red...guess I need to also explicitly give those colors in the xyouts commands.

What's the "default" color? Does it use whatever is assigned to 255? Cause if so, that would explain it. (And maybe I changed my custom color table? this is starting to ring some bells...)

kelle

@colors_kc ; loads custom color table gives colors names
color_line = black
IF ~KEYWORD_SET(ps) THEN BEGIN
;set up for display to screen
set_plot,'x'
device, Decomposed=0 ;make colors work for 24-bit display
print,'ye'
color_line=white
ENDIF
plot, w, spec, [...], color=color_line
