93TurboSi

I want to get a color matched guage pillar from autometer but they have 2 colors of gray (shimmer gray and clear gray). Does anyone know a way to determine which color is in my car. I know the civics have different colors in them to because my old 93 civic cx pillar was a brighter gray then my 93 Si. The main difference between the 2 cars was the cx had all gray interior and the Si has black interior but the pillar and headliner are gray. I've looked through the archives with no luck finding real answers. Please help!
