In order to meet [WCAG 2.0 accessibility standards for color contrast](https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html), authors **must** provide [a contrast ratio of at least 4.5:1](https://www.w3.org/WAI/WCAG20/quickref/20160105/Overview.php#visual-audio-contrast-contrast), with very few exceptions.
An additional function we include in Bootstrap is the color contrast function, `color-contrast`. It utilizes the [WCAG 2.0 algorithm](https://www.w3.org/TR/WCAG20-TECHS/G17.html#G17-tests) for calculating contrast thresholds based on [relative luminance](https://www.w3.org/WAI/GL/wiki/Relative_luminance) in a `sRGB` colorspace to automatically return a light (`#fff`), dark (`#111`) or black (`#000`) contrast color based on the specified base color. This function is especially useful for mixins or loops where you're generating multiple classes.
