Decorators and designers sometimes tend to be guided by their own subjective color propensities. This may lead to misunderstandings and disputes, where one subjective judgment collides with another. For the solution of many problems, however, there are objective considerations that outweigh subjective preferences. Thus a meat market may be decorated in light green and blue-green tones, so that the various meats will appear fresher and redder. Confectionery shows to advantage in light orange, pink, white, and accents of black, stimulating an appetite for sweets. If a commercial artist were to design a package for coffee bearing yellow and white stripes, or one with blue polka dots for spaghetti, he would be wrong because these form and color features are in conflict with the theme.
