266. COMPOUND COLOURED PAINTS

The various colours that may be obtained by the mixture of other
colours, are innumerable. I only propose here to give the best
and simplest modes of preparing those which are required for use.
Compound colours, formed by the union of only two colours, are
called by painters virgin tints. The smaller the number of colours
of which any compound colour is composed, the purer and the richer
it will be. They are prepared as follows:


267. LIGHT GREY

This is made by mixing white lead with lamp-black, using more or
less of each material, as you wish to obtain a darker or lighter
colour.


268. BUFF COLOUR

This is made from yellow ochre and white lead.


269. SILVER OR PEARL GREY

Mix white lead, indigo, and a very light portion of black,
regulating the quantities by the shade you wish to obtain.
