Suitable amount of emphasis varies with every problem. Emphasis may be regarded as a graded scale and the greatest amount of force that can be used with good taste will come at a different point on this imaginary scale. Surface to be considered as background against which the pattern must be seen, should register emphasis at a point near zero on the scale.
The concept of dominant, subordinate and accent refer to the relationship of the parts in the total concept of emphasis. Of these three levels of emphasis, dominant means most obvious, subordinate and accent are also important consideration in the whole design. Subordinate means second most obvious and accent means least obvious, thus can be called more, less and least.
