Due to variances in mineral oxides mined from different locations, minor colour variations may be noted from batch to batch and are beyond our control. A formulation may appear different by visual comparison - however the applied colour would be the same, if not very similar, to the previous batch and is therefore deemed as similar as can be for a pure, natural, mineral colour product. The only way to achieve exact colour every time is to add FD&C (synthetic) dyes which many commercial mineral cosmetic companies do - then it is no longer a PURE mineral product.
