Wrong again at the swap

[Burd]

I have buddy with a 1970 Z28 , I detailed under the hood for him and help him make the already nice car nicer, one seat belt in the rear is all shredded.
I was at a swap and bought a roll of green, ( his car is green on green) I was geeked, I didn't call him, I just bought it. It's a lighter green. I hate when that happens. Now I'm stuck with a $100 roll of green webbing. Lol. There's prob enough to do 2 cars.
How many shades of greens are there? Lol
