Here's a quick fix for you until it's changed. The color they actually use is a light beige very similar to the forum color, but it appears differently in game.
1. Go into factions.txt in your Mount&Blade Warband\Modules\Native folder
2. search for "vaegir"
3. It should come to this
插入代码块:
line 0 fac_kingdom_2 Kingdom_of_Vaegirs 0 xxxxxxx
0.000000 0.000000 -0.050000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.900000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 -0.020000 0.000000 -0.020000 -0.050000 -0.050000 0.000000 0.000000 -0.100000 0.000000
4. the "xxxxxxx" is where you'll put a decimal code in for the color you want to use. I chose 3478348 which is a nice dark purple.
If you don't want to choose your own color feel free to use 3478348 to save yourself some time.
5. To find a hex code for any color go here http://houseof3d.com/pete/applets/tools/colors/
6. To convert it to dec go here http://flor.nl/dec2hex.html . Just enter in the hex code and click anywhere, and it will give you the corresponding dec code
7. Take that dec code and put it where "xxxxxxx" is in the factions.txt file.
8 Sorry, needs a new game to work.
Ask questions if you have them.
