I noticed my palette is looking very juicy and colorful for my Lilly Pad paintings! I use Golden Open Acrylics and a Mijello Palette that seals. I can keep a palette going for a year or more if it gets regular use, refilling and maintenance. I don’t put water in the palette like other acrylics, that would be bad news! It’s the advantage of Golden Opens. The paint doesn’t skin over, it gets thicker, and impasto pasty gooey! That’s what I love! I was accustomed to oils and I use it the same way.
