Opponent-Process Theory of human vision

The opponent-process theory was proposed in 1982 by German physiologist Edwald Hering. In his theory he explains that our ability to perceive color is under the control of three opposing systems which are generated by the three different photoreceptor cells found in the retina of the human eye.

Experiencing color

The ability to experience color can help us in a variety of ways. Colours convey meaning, connect, communicate functions, and help us to distinguish information.

Using the Von Restorff effect to guide users

The Von Restorff Effect refers to our ability to remember items that stood out from the rest, or extract items that stand out from the rest of information with greater immediacy.

This effect occurs when readers scan, or remember a dashboard interface that applies some of the principles that support this phenomena, meaning things stand out as unusual.

As designers we can take advantage of this effect to direct a readers attention. The effect is achieved by various means and only when applied sparingly:

  1. Use of highlighting
  2. Use of heavier font weights
  3. Use of bold colors

A woman with rainbow vision

Concetta Antico was found to have a wider spectrum of color perception than most of us do. According to news, she sees about 100 million colors, because her eyes have a fourth receptor causing a condition called “Tetrachromacy”. Given the fact that my SLR can only do 16.7 million, that IS impressive.
