Harmonious Consistency
The colour scheme should be determined by aspect and by the use of the particular apartment. A sunny room should be treated differently to one with a north-east aspect, in which an appearance of warmth is desirable. Furniture, too, must be considered, reds being an unsuitable setting for oak as a rule, while mahogany is best associated with delicate greens and greys.
It is a reasonable assumption that the training of the student should result in greater discrimination, and when the exercise consists of representing, it is a matter of careful approximation of colours and values. In original design the harmonious effect depends on the individual, who, in early attempts in colour, jumps at it, being unconscious of any guiding principle.
