I work on a small tool for our local league, for keeping our results and who plays what factions etc. I consider visualizing some statistics and presenting them in uniform way - each faction has its own colors for every kind of presentation. It is quite easy to just copy the colors from eg. army builder, where each faction has it's own specific color in layout elements, eg: YJ: darkorange, Ariadna: forestgreen This is all cool and nice, but the same color is propagated through all sectorials of specific faction. Are there any official materials issued by CB with some fixed set of colors for both vanilla factions and sectorials? In worst case I will just play with different shades of those basic colors, but I think it's worth asking about.
There was a nice pie chart that showed all of the vanilla + sectorials for something that seemed official, and that had different colors for each (I think it was the main faction color and each sectorial was a different shade of that color), but I don't know if CB actually produced it themselves. The latest one I found (granted, in 20 seconds of looking) was from season 9 and it was a mono-colored bar graph.
I based my initial post on what I've found on CB blog, where they present ITS statistics annually. In those comparisions, it's always single color for eg. factions popularity.
I know for the Nomads that the primary color of each Sectorial is one part of the Nomad flag. Corregidor is primarily orange, Bakunin primarily white, and Tunguska primarily black.
Corregidor is more red than orange these days. IIRC the fluff says red too. The same colour concept largely plays-out with PanO, when you look at the face plates. Acontecimento is green, NeoTerra is red, Varuna is blue; Military Orders is the hiccough here. I think trying to represent every sectorial by a colour will get confusing, however. You have too many sectorials, so the colours will come down to subtle variations. Is that a Corregidor red or a NeoTerra red? Is that shade of green Acontecimento or vanilla Ariadna?
You could do stripes, PanO are blue, NCA are blue with a thin red stripe, SAA grey a green stripe, etc.
Was literally just about to post my suggestion but colbrook got it out first - two colour situation seems smart. Might fall apart a bit for CA though, where everything is red and black.
Vanilla CombArmy: Purple MAF: Purple with red stripe (red faced monkey men) Shasvaasti: Purple with yellow stripe (matches unit icons) Onyx: Purple with black stripe (or is that an Onyx stripe?) Nomads are the trickiest as both Vanilla and Corregidor are Red, might have to arbitrarily use another colour like yellow for CJC.
