SIXTH STONE—LIGHT BROWN.
But what an eye for colour! What a gift for the realities and essentials of tone to be able, without any mixings of paint or other analytic experiments, to divine straight away just what colours are needed, and prepare stone after stone with the absolute certainty that the combination would produce such a result!
SEVENTH STONE—LIGHT BLUE.
To illustrate the almost marvellous capability of the colour-expert in analyzing the colours of a picture submitted to him, one may mention that the late Sir Charles Eastlake, P.R.A., once ventured to assert that there were sixteen colours or shades visible in a picture by Van Dyck. The lithographic colour-expert declared there were only eleven. Accordingly an accurate copy was painted at the National Gallery of the picture, so accurate that it was difficult to discern a difference between the copy and the original. This was duly analyzed and placed on the stones, eleven in number, and the eleventh printing disclosed an exact facsimile of the copy, and therefore of the original.
EIGHTH STONE—PINK.
NINTH STONE—MEDIUM GREY.
