Blue.
Dip one of your pencils into the blue, and work it on the pallet; then make
a stroke upon a clean piece of white paper, which compare with No. 4, of
the blues; if you find it of the same tint, you have got the proper colour;
but if not so dark, you must rub more colour off your cake, till you find
it exactly as dark. Next, to make the tint No. 3, take the least water you
possibly can with the very point of your pencil, and mix it in the blue with
the pencil, and make another stroke on your paper to compare that with the
tint No. 3; if you find it too light, you have taken too much water; in that
case, to make the tint No. 3, you must take a little more of the blue, No.
4, and by these means you will find out the exact tint of No. 3: when you
have made No. 3, take a little more water, as before, to the tint No. 3,
and mix it; then make another stroke: compare that with No. 2, and No. 1;
if it be too light for No. 2, it may be exactly alike to No. 1; in that case,
take a little more of the dark blue, No. 4, and mix it again; then take another
stroke, and compare it with No. 2, and proceed in that manner till you get
the exact tint:
in the same manner you will be able to make No. 1; and by practice, become
familiar with the method of making the tints to such a degree of nicety,
as will enable you to make every other tint without the least difficulty,
though I have now only shewn you for four tints. In painting the various
blue flowers, you may have occasion to make use of a much greater variety
of blue tints; but as they are all made with adding either more water or
