First, I went to Snopes to see if anyone else had analyzed this particular collection of epitaphs. No luck. I did, however, find an entry about a real gravestone and cropped the associated picture to show what an unmodified gravestone can look like. As is typical of real gravestones, the letters are incised into the stone and are not painted in. This pattern accords with my own observations in cemeteries, including the locally famous Hope Cemetery in Barre, Vt., which is a couple of miles from my home.
