After 37 years in the printing/dyeing/finishing I can promise you no two will ever see the same color the same way

Is it blue, med blue, dark blue, navy blue, med red blue...is it 10% off shade or is it 20?
I've seen an original crate motor, still crated up, sitting in JimCarters front room but can't remember the year. I'm pretty sure it was a 216. However, after sitting for years, especially under the lights, the color is bound to be off some. I don't usually get into the engine color discussion but in the end we usually always paint them the color "we" like best. Heck, for me I just paint them Plasti-Kote Universal Grey #202 and call it close enough!
.....You guys just wait until Denny see's this post. LOL
