What colour is your master cylinder lid?

This may seem like a weird question, but I need to know what the stock colour is for the master cylinder lid. I have one on the car that I'm restoring that is bright blue in colour, but that's a different colour than the ones that are on my other CRX and my gf's CRX. I'm just wondering if maybe that M/C was off of another car. It's still a 7/8" size M/C by Nissin.

Please understand that I am restoring this car...and I am being ultra picky with the small details. Your help is appreciated.
