The following info graphic is intended to demonstrate the nature of human contrast sensitivity, using text samples to connect the abstract science to practical reality.
It's based on infographics I originally created several years ago. More info in ALT.

This is a chart of the human contrast sensitivity curve. A blue line curves down to the right where the Y axis is contrast sensitivity, and the X access is spatial frequency, increasing toward the right. An increase in spatial frequency means elements are smaller and thinner. On the right of this info graphic are samples of text from very large and bold to very thin and small, with red lead lines indicating approximately where those samples fall on the contrast sensitivity curve. All of the text samples are at the exact same CSS color of #c7c7c7, the top very large and bold headline is legible but as the fonts become thinner and smaller they literally fade out as if becoming lighter gray, even though they are all at the exact same color.

Now looking for volunteers for a color vision study.
We are particularly interested in individuals with color vision deficiency, however all vision types are welcome, age 21 and up.
If you are interested please email: cvdstudy@myndex.com
