For those who don’t know, the main difference between craft store paints and artist grade paints are:

- ratio of pigment to binder (craft store paints have less pigment)

- pigment quality (craft store paints are usually larger grain and may sometimes use unsafe pigments)

- color purity and consistency (craft store paints may contain traces of unintended pigments and may vary between batches)

- color variety (craft store paint manufacturers are NOT going to be paying extra for rare pigments)

- lightfastness (craft store paints may fade quicker due to lack of UV protectant additives)

- binder quality (craft store paints may use cheaper, more toxic binders)

Otherwise they are the same stuff, it’s kinda hard to screw up mixing acrylic binder with a pigment.

Check that your paint has the ACMI Approved Product seal.
