Read the label carefully before you go back and get shown up by a pimply teenager in the Paint Department - there's a new Feature on the market where they put the turquise tint in the paint on purpose, then it evaporates as the paint dries.
So you can see at a glance what has and hasn't been covered with that coat, and get it even - then the paint dries and the purple goes away and leaves you with White.
If you are covering another color or a brilliant white prime coat it makes it easier, and if you want to apply another coat that's when the tint would really make it easier by showing the missed spots.
