What color is my truck?

[87chevy350]

Hi, I have a 1987 chevy k10, I don't know if this is the original color or not cause the tuck was originally 2wd and pieced together by the other owner and didn't tell me he did it until I got the truck home and pulled up the carpet and saw the 4 wheel drive hump caulked in. In the rpo codes it says that it is medium blue but it seems like light blue metallic. I wanna know cause I need to get touch up paint to match it thanks
