69 Chevy - Seeking Upholstery Color Match

[69 Mischief]

Tommy and I are new to this forum. He has a 69 Chevy C-10 (in the family since it was new). We're making some cosmetic improvements, starting with re-upholstering the bench seat (bed replacement also but that will be a separate thread).

We took it (the seat) down to the Hills of Kentucky last week to a friend who does this work and she had some vinyl in stock that was close, but when we got the sample home we found it's just not "close enough" to the original color.

It's a really cool turquoise blue. I searched all over online trying to find what the original color might be and came up empty handed and frustrated, then I found this site.

We've never done any restoration work and we're on the lower-end-of-budget-and-time-plan but we care very much about getting this right.

I appreciate any suggestions to find a good match for the original color!
