As mentioned in my other reviews I like these for their almost non-toxic nature and it's great to not have to be concerned with potential health issues when painting. But I've had time now to give these a more thorough workout and these Natural Acrylik paints have two big problems:
1) the color shift from wet to dry is difficult to deal with and makes it very hard to mix the same color and use it again, even if mixing only two colors. The mix will usually dry quite a bit darker, and I have to wait for the new mix to dry to see if the color/value is correct, if it's what I want. Then I have to try again and again, adjusting the mix to finally get it right. Regular acrylics from other companies (like Golden or Liquitex) don't have as much color shift from wet to dry.
2) If wiping away some newly applied paint that has been applied on top of dry paint the new paint will re-activate the dry paint under it a bit and will also wipe away some of that dry paint, even if the dry paint has been dried for a week or more. Big drawback, and very troubling, I have to go back and fix it.
3) As mentioned in my other reviews (07/20/2025) this company needs to do a better job with labeling their products. Example: Pthalocyanine Blue should not be labeled Royal Blue. The term Royal Blue does not tell me specifics about the color, it's a fancy trade name that pulls the product into a cheap craft realm instead of a professional realm. Plus the tubes still do not have any pigment labeling, lightfastness labeling, etc., at least not from my last purchase of the paints.
Until they can get these Acryliks more into a professional level I'm going to continue to use the regular acrylics and just ventilate my studio well.
