A Simple Overview Of Human Vision
Light is focused by the eye’s lens onto the light-sensitive cells in the back of the eye, known as the retina. The cells we are most interested in are called cones, which are responsible for our daylight and color vision. A different kind of cells, called rods, gives us night vision, but rods are not particularly helpful for tasks like reading, and rods essentially shut down in daylight conditions. Standard or “normal” vision uses three cone types. They are sometimesbut inaccurately called “r...
Color Is Not Real
Is color not real? That’s a provocative statement for an article on color and contrast. But the reality is that “color” and “contrast” are not strictly real in an absolute sense. “Colored” light is simply light of different wavelengths or frequencies, like different notes on a piano. In fact, the scientific names for the cone cells in our eye are L, M, and S cones which stand for the long, medium, and shortwavelengths of light they are most sensitive to. The L cone actually has a peak sensiti...
The Imaginary Reality Of Perception
What might not be apparent from the above discussion of the mechanics of our vision is that colors are just perceptions, and as perceptions, they are affected very much by context. In other words, the nature of the surrounding visual material has a substantial effect on the colors and contrasts that we perceive and how we perceive them. In this graphic, both yellow dots emit the same exact “colors” from your monitor, yet they look decidedly different. And while such images are often referred...
There are many forms of contrast, such as contrasts of size, shape, or position, contrasts of content, theme, or emotion. But for the bulk of this article, we will focus on “perceived lightness contrast”. This is closely related to luminance contrast, as luminance is a measure of light, which we perceive as lightness/darkness/brightness. In other w...
During this transitional period, where we know that existing guidelines are expected to be revised or replaced, it’s helpful to see the road ahead. Here are some things designers can do now to improve readability, compliance, and actual accessibility while being better situated for future guidelines.
The printing press with movable type has existed for over a thousand years in Asia. Nearly 600 years ago, Johannes Gutenberg introduced the movable-type printing press to the western world. Comparatively speaking, the internet has been with us for a fraction of that time, and the transition to electronic type still poses challenges for good readabi...
