COLORS THAT ELUDE ME

I believe the toughest colors of nature still eludes even the finest paint mixers.

Robin's egg blue: This always comes out powder blue.

Blood Red: Never quite right.

Emerald green: again, it tends to drift to lime greens.

Just to name three.

The main reason I believe is the optics of size. Once you attempt these on a larger surface? Our eyes change on how we view and perceive.

Just something stupid I have noticed.
I would agree that certain colors will play some tricks on your eyes after looking at them for so long during a paint job. I painted a 46 Ford truck that Seafoam green color and by the end of that my eyes were playing tricks on me.
