Orange Colour Tints.
These are likewise composition tints, made by mixing gamboge and vermillion
together. From what I have said of the manner of mixing the other tints,
and by referring to the tints themselves, you will easily find out the method
of making these. The brighter the orange colour is wanted, the less vermillion
must be added: in some cases, the lightest tints of an orange colour may
be put in with a full strong yellow, as a nasturtium: some high-coloured
wall-flowers and bleeding hearts are almost an orange; and the very lightest
tints of them will be better expressed in yellow. It is easy to make the
lightest tints darker, but you can never make them lighter in water colours.
The various degrees of shadow for orange colours, are what I have shewn in
gradations in the tints, therefore we will now proceed to give some directions
about the
Yellows.
You may observe that gamboge is the brightest yellow we have; consequently
all yellow flowers, such as yellow tulips, yellow roses, yellow jonquils,
and other yellow flowers, must be laid in with it; yet their shadows are
not made by working the yellow stronger, as in the pink and blue, but made
with different colours. In the case of faint pale yellows, the yellow should
be worked thin to put in the first and second tint, which may be done by
strengthening the yellow; but, in a full yellow flower, the first degree
