SAPC Contrast NaN

SAPC Visual Contrast Demo

This is the Basic SAPC contrast method using JavaScript.

Just type in color values as #hex, rgb(), or HTML name

then navigate away from the input field by either

pressing TAB or clicking elsewhere on the page.



Scroll down for a set of type samples in

sans and serif fonts. On the left is the level,

as in "L80". This means that row wants to see

at least 80% contrast (positive or negative).
