If it is cheated, as we ourselves are apt to be, into accepting spurious indigo, made up of chemical preparations, it speedily discovers the cheat and refuses its colouring.

Perhaps this sympathy is due to a vegetable kinship and likeness of experience, for where cotton will grow, indigo will also flourish.
In printed cottons or chintzes, there is a reasonable amount of fidelity to colour, and if chintz curtains are well chosen, and lined to protect them from the sun, their attractiveness bears a fair proportion to their durability.
An interlining of some strong and tried colour will give a very soft and subtle daylight effect in a room, but this is, of course, lost in the evening.

The expedient of an under colour in curtain linings will sometimes give delightful results in plain or unprinted goods, and sometimes a lining with a strong and bold design will produce a charming shadow effect upon a tinted surface--of course each new experiment must be tried before one can be certain of its effect, and, in fact, there is rather an exciting uncertainty as to results.

Yet there are infinite possibilities to the householder who has what is called the artistic instinct and the leisure and willingness to experiment, and experiments need not be limited to prints or to cottons, for wonderful combinations of colour are possible in silks where light is called in as an influence in the composition.

One must, however, expect to forego these effects except in daylight, but as artificial light has its own subtleties of effect, the one can be balanced against the other.
