Red Terra-Cotta.

—Use equal proportions of burnt sienna and white lead. The tone may be varied by the addition of either of the umbers and the chromes. A good bright terra-cotta is also made by using Venetian red as a base and colouring up with ochre and a touch of lake.

Regal Purple.

—Mix together four parts of white lead, two parts of cobalt blue and one part of carmine lake.

Roan.

—Mix black with half its quantity of red and add a very small proportion of blue and white.

Rose.

—Five parts of white lead mixed with two parts of carmine give a rose colour that is suitable for inside work only. An admirable rose colour may be obtained by using zinc white instead of white lead, as the zinc is a much purer white than the lead, and hence gives a purer tint.

Rose Carnation.

—Mix together one part of rose madder and eight parts of oxide of zinc. This is a beautiful colour, but the madder is too expensive for use except by artists.
