Q: Why most pool tables have a green felt?
A: Because it was originally played on grass. Louis XI from France was the 1st one to order a pool table in 1470.
Recent studies show that ‘green’ is actually easier on the eye which allows you to play longer without eye strain, and some claim it helps with your depth of vision (needed for long shots).
The most recent development by DuPont shows that a light blue color gives the best vision of the balls on the table.
