If you thin it, it could change the color.

Last year my wife wanted to repaint the tops of our porch rails. I pulled out the several-year-old Behr Premium Ultra Pure White latex semigloss paint and it was thick, so I thinned it with water. She painted--job done. Months later we realized that the paint was a rather pretty shade of light tan! So, I bought another can and we repainted and it's fine.

Who woulda' thunk?
