Abstract wallpapers are always excellent choices for contemporary art lovers and people who like dreaming away. Digital art has the power to create unexpected graphics that please the eye, and offer viewers a psychedelic visual experience. Computer generated fractals or just photographs taken from unusual perspectives can help people evade from their environments into a new, creative world of shape and color. When admiring abstract pictures, you can get the impression of an unreal experience, comparable to that of a dream, a fantasy or of an altered state of consciousness.
Red is said to have a stimulating effect on people. Researchers found that red could affect people's reactions, leading to more rapid movements and a greater force. This stimulating effect can also have negative consequences, like agitation or lack of concentration. Scientists found that exposing students to red leads to a poor performance on a test. So, if you plan to change your desktop wallpaper before an important exam, it might be a better idea to choose cool colors and avoid red.
