More in the appearance of a yellow or amber colour. A lot of settling, which is surprising given its transparency. Settling is very pale almost appearing like chalk in the bottom of the tube. The solution looks like an ale beer. There is not much coloured pigment present on the paper but it looks warm. No mould, no unpleasant smell.

Soft orange tint with granulation evident from outside of the tube. The pigment has coagulated into clumps. The colour is plentiful and it seems to want to stay with the paper rather than get left behind in the test tube. Rich warm opaque that is also soft and dense.

It looks like I tripled the quantity of pigment. It’s heavy, opaque, muddy, and very present. The colour is intense and deep from the top of the tube to the bottom – although there is still a considerable amount of settling in the bottom of the tube. The pigment is not sitting in the solution anymore but is bound or held around the paper.

Just as I expected of the Indian Red pigment... with its random and imperfect coverage and settling. It has a blue undertone.

A highly transparent solution but a very deep colour in the bottom of the tube. Some clotting of pigment is evident on the paper. The subtle colouring and stains are completely irregular. There is an uneven distribution of pigment – dark black particles left like a residue on the surface.

My favourite pigment is Potters Pink because it defies what we typically recognise as a red pigment. Very soft, hardly staining the paper but it is still present and forms soft small granulations over the paper. All pigment settled and the solution is virtually clear.

Irregular stained stripes have been dictated by the rolling of the paper into the tubes. Colour sits on the paper.

Oh goodness, it’s so dramatic and NOT RED at all! Lovely lines of granulation where the pigment particles have moved with the folds and bend of the paper. Soft granulation solution is tangerine, and the paper is dirty musty brown violet… weird as! I cannot explain the outcome of this pigment and its different presentations.
