Windsor/Newton is what I like to use. Always check out the amount of pigment in the paint you use. That’s the general measure of the quality of oil paint. Many people spend a lot of money on series 3 and series 4 paint when series 1 or 2 will do. If you are just getting started in painting, be proud of what you do, but don’t fall into the trap of thinking that the more money you spend, the higher quality your work will be. If you live near a university, check their bookstore close to finals time. If they sell art supplies at the bookstore, they are usually trying to liquidate their stock at the end of the semester and you can get some great deals.
