Paint never seems to behave the same. Even the same paint doesn't, you know. In other words, if you use the same white or black or red, through the use of it, it never seems to be the same. It doesn't dry the same. It doesn't stay there and look at you the same way. Other things seem to affect it. There seems to be something that you can do so much with paint and after that you start murdering it..
