Question for the Ravens Fans?

[markee]

I am painting up a Ravens team. I ahev assumed that their helmets are Black?
The decals that I have for the Helmet stripe are a dark purple and DO NOT show on the helmet.
Have I made a mistake or are the decals just not compatable? Has anybody else had a similar problem? Are the helmets are color other than black?
The decal sets that are available to us today are fantastic. Thsi is the 1st conflict that I have had.
Help or advice would be appreciated as I am making a 60 player team.
