The nice man said that tube colors are formulated differently than pans! Who knew? Tube paint loses it's dispersant and conditioners when it dries and can be hard to re-wet without the conditioner and dispersant.
Another video explained that tube paints do not contain the preservatives that pans have.
With a wonderful 50% off coupon for my local art store, I bought 2 colors:
- Burnt umber because it cracks up when I dry it in pans and is very hard to re-wet
- Cobalt because I've had trouble with it getting moldy in my old plastic palette with a rubber seal to keep the paint moist.
I am in love! These colors come in a very large white china pan, 2 1/2 inches by 3 1/4 inches. They rewet instantly and make a wonderful creamy wash in just a few swipes of the brush. The pans can stack and there is also a nice wooden holder for the pans. They are pricey; you're getting a lot of paint in this size pan. I'm saving my pennies for more colors!
