Yeah, that means that they sprayed their greens. The blue is a dye called tracker so that the guy spraying can see where his last pass was so he doesnt skip or overlap too much. What you touched on your ball could have been fertilizer, fungicide, herbicide...anything.
Because you had it on every green I would guess you were one of the early groups following the sprayer. This is exactly why I promote spraying in the evenings unless its a soils spray that gets watered in.
