LOL :-) just kidding. When clay ochre are used as pigments it is the amount of silica and iron in the clay that effects the color of the paint. I can see what you are saying about the color of the clay when grinding it. I will have to remember that when grinding pigments. Water is used when grinding the pigment in to a powder the clay turned an orange color then then when I mixed in the poppy seed oil and let it dry it returned to a more stable color. In all seriousness Magnus I had know idea the water levels effected the color of the clay. Thank You. <br>
