True, kevlar on its own it that wierd colour, but it is often interwoven with carbon fibre in varying proportions to get the required properties in the final material. I've seen it ranging from a pure beige/yellow to almost black with yellow "flecks"That explains the colour of the decals. I was wondering about them, but now you mention it, I recall that all the “raw” kevlar I’ve seen IRL (which, I admit, isn’t all that much) is this odd, pale yellowish/greenish colour like on the corners of the skid plate in your photo of the real thing.
