The following are the combinations of five hues which occur: brown, green, blue, dark yellow, and pale yellow; orange, lilac, white, yellow, and olive-green.
Combinations of four hues are much more common: e.q., red, white, yellow, and black; deep yellow, brown lilac, white, and pale yellow; lilac, yellow, white, and green; yellow, blue, white, and brown, and yellow, blue, white, and olive-green.

Sometimes the tints are as few as three, the ground in these cases being generally of a hue used also in the figures.

Thus we have yellow, blue, and white on a blue ground and again the same colors on a yellow ground.

We have also the simple combinations of white and yellow on a blue ground, and of white and yellow on an olive-green ground.
In every ease there is at harmony in the coloring.

We find no harsh contrasts.
