What Oil Paint Should I Choose?
Updated: Sep 23, 2022
You're new to the oil painting scene but you have to start somewhere. Here is a breakdown of what you're looking at.

Presupposition: You are shopping at a fairly regular art store- not fancy and not a basic craft store.
Cheapest
In the cheap section you are going to find brands like:
Van Gogh
or the store brand ( at Hobby Lobby it's called "Master Touch")
Gamblin 1980
Winsor & Newton's Winton Colors
are both in the cheap section but they are much higher quality than Van Gogh or a store brand. They essentially a student line vs the fancy artist line. But since they come from good brands they are still rich with pigment.
If you know you are going to waste a ton of paint just learning how to use oil paint then getting the cheapest thing might be best for you. However, if you can affordable Gamblin 1980 or Winton, go for it. You don't want to waste time thinking that you are terrible at mixing colors if the real problem is the quality of your paint.
