I recently purchased the Earth Colours Paint Set and couldn't be happier. I have tried regular acrylics and can't stand the fumes. I also wanted something that was safer for the planet. I've been trying the Liquitex Bio-based line as well as these paints in tandem, and I can say that I prefer these by a landslide. When the others run out I will not be buying them again. I wold love to see more colours available, but regardless, I'm thrilled!
