When you’re talking about interior paint, one of the big catchphrases these days is zero-VOC paint. VOCs refers to Volatile Organic Compounds. Without going into a big chemistry lesson, these things are not good for people or the environment, so removing them is a good thing.
The problem is that when you add tint to the paint to get a specific color, you put the VOCs right back in. There are companies which offer pre-tinted low-VOC paints in a variety of colors. But remember, if you have the paint pro add anything to alter the color, you’re defeating the purpose.
A true zero-VOC paint will offer a powdered tint that you add yourself, so you can choose from a wider variety of colors and still get the health benefits you want.
