Artist grade paint is obviously more expensive than student grade paint.

But when do I realy need artist quality paint to obtain good paintings?

In other words, when and how big, and how important, is the difference?

I started experimenting with both paint qualities and mixed all possible combinations of quality.

(artist+artist, artist+student, student+artist and student+student.)

I mixed a grey colour with French Ultramarine and Burned Sienna. (both Winsor & Newton)

I also painted twice with the same mix: wet on damp and wet on wet.

From this test I can see that there is less granulation when using an Artist+Artist mix in wet on wet technique.

If this is important then Artist paint is the way to go.

No doubt there are a lot more differences to discover.

More tips and advice about testing paint quaity?
