From: Why are there squished peanut butter cups in my underware?
1990 was a weird year for Dark Red Metallic. Although the shade of the color itself changed from the `86-`89 version, early `90s still used the 68 RPO code. At some point during the `90 run, the code changed to 74, and was also known as Brilliant Red.
Look for the RPO sticker (for `90 it's located on the underside of the storage compartment lid between the seats, and make sure the VINs match as this part is commonly donated from other Vettes).
The actual paint code will be WA???? listed at the bottom of the RPO sticker.
