Only partially right. A more precise & correct answer is:
"The notion of shooting a projectile of paint (paintball) from a gun (marker) was first pondered back in the mid-1960's by Charles Nelson, the co-founder of the Nelson Paint Company.
Charles Nelson had patented a number of devices that foresters could use to mark timber for removal. One of these was a squirt gun that sprayed a jet of paint.
A ball of paint (aka the paintball) was invented because the Nelson Paint Company was asked by the U.S. Forestry Service to come up with an efficient way to mark trees from a distance. The problem was that trees needing to be marked were located across streams or some distance away. The squirt-guns had a limited reach.
Another use for the newly invented paintball was for ranchers, so they could mark stray cattle from a distance. Charles Nelson developed and produced a pellet that could be shot from a gun, which he called a "marker"."
