When solidifying the graphic design fundamentals behind the design and layout of an app, simply questioning how things will look is not enough — "you have to think about how they feel. We’re not talking about haptic feedback, either. Ever since Johann Wolfgang Goethe studied the physiological effects of color, we’ve been obsessed with using color to produce physical and emotional effects."

Especially in the modern age of design, color takes center stage in many brands’ philosophy of design. Healthcare, business, and government will more often than not use blue, "as it gives off a sense of trust and professionalism. Green is seen as a youthful color that’s full of energy — and, of course, reflects a sense of environmentalism and closeness to nature. Red is energetic and impulsive, giving off the impression of speed, efficiency, and power." 

Every color visualized as well as the colors intrinsically associate with certain brands, will imply something; either directly or indirectly. This helps designers to drive home the perception of individual brands.
