One of the hallmarks of our age is that computers have given us the ability to modify images endlessly. Using Photoshop and similar programs, you can change almost everything about an image. One of the parameters that you can adjust is saturation. This gives the color more depth and intensity. Cactus flowers do not need adjustment to their saturation. In fact, if you add saturation, the flower loses detail. Cactus flowers really are this intense color. There is no false advertising here with these flowers.
