I purchased some of this brand of watercolours to try them out. Unfortunately as I squeezed them out into my palette I could straight away see the difference between them and my other brands. They were very runny and threatened to spill out of their places. One of them, the cad red seperated into 2 parts, one oily looking (possibly the binder) and one with pigment colour. I will keep using them up and watch how they perform when painting etc.
