I wouldn't go with white, personally. There's one of the source books - I want to say either the Confederation Handbook or Victory Streak, possibly both - that suggests Kilrathi largely use deep reds and browns. (Feel free to correct me, all y'all).
Which is a shame, really - the white looks good, IMHO.
Got it. I will try to change the color set.
I noticed that in CCG they have nearly white / sliver-themed cloaks (e.g. http://ccg.jetlag.us/Kilrathi/pilot/k-p-deathfang.jpg ) , but their clothes are still basically brown as a whole. This reflects the designer's overall color matching skills. It's a bit difficult to achieve this at my current skill level. Ah, what should I do ...
There is also a problem, I think... perhaps... Action Stations has emphasized the differences between / among Kilrathi clans, rather than emphasizing that they are a whole. So how to reflect this difference in color matching is a problem.
BTW: I recently encountered an interesting problem. My laptop has a TN screen. This is OK for line drawing, but it is troublesome for coloring. Looking at the screen from different angles, I see that the colors are quite different. In addition, I get used to Night Light mode ON. This caused even more color distortion...
