There are two levels of reading color. The first is the overall color of the image and the second is the content level. The overall color is to give a certain mood or certain feeling to the image. Like a warmed up image for a more positive warm feeling of the person that it portrays. The content color is to give a certain reading. It’s like a signal or a wink. A simple example is red. Red is the color of passion. But it is context of the image that determines the reading: Under certain circumstances red is the color of danger. But whatever the case, we must always understand that the entire world is in color, and for most contexts, there is no hidden meaning behind those colors. They just are what you see. But for some other contexts, especially fine art images, colors are selected because of a particular reason. The warmth or coolness of the image conveys an intended ambiance. Listed to the left are the most widely accepted “readings” of colors. A fun exercise is to always question why certain companies have certain colors in their logos. Most likely is because of the readings and emotions they want to convey.
