Minorities are important and enriching the whole. If you take a look at this picture you can see it very clearly.
What would be the image without the blue structures? A surface-filling color without greater contrast and effect.
Even in real life minorities give an important contribution and a supplement, so that the “whole” become versatile and varied as it is. Without minorities it will degenerate to a boring uniform mass.
I shoot this picture on the beginning of November 2015 in Melbourne in the garden of the National Gallery of Victoria. (http://www.ngv.vic.gov.au)
