Is it worth using non-VOC or low-VOC interior paint?
Just as an FYI, if you're going to heavily color the paint, be aware that a lot of tints are not low-VOC. From this site

Low or no Voc (Volatile Organic Compound) house paints are great, since they have little odor and limit harmful chemicals in the air. But tinting the paint often defeat the purpose by adding unwanted VOCs back into the paint.
To make sure the air in your home is VOC-free, use factory tinted no VOC paint, or paints that use a VOC-free colorant
