That's even more different from Alpine Green than I thought it would be. There are some specs on the stir stick that look blue-er, and around the rim has some dried spots that look blue-er- especially on the right side. It's more like Alpine Green but a tad darker.
60-66, how well is that paint stirred, and could you possibly brush a couple coats on a small test piece to see if the color changes when it dries? Very interesting to see original paint!
