Vordarian was maroon and gold, close enough that they'd probably be considered the same by heraldry standards. I can imagine the discussion that might lead to the colour scheme. "We want the radiation symbol to glow gold, for visibility, so what other color should we use for contrast?" "Hmm. Use the wrong color combination and we'll get some Count making a stink." "I know, let's use Vordarian's colors! Everyone can look at the gross, gigantic bugs and think of him! The current Count Vordarian is decent enough, but he's not about to call attention to himself."
