 All Bootstrap colors are available as Sass variables and a Sass map in `scss/_variables.scss` file. To avoid increased file sizes, we don't create text or background color classes for each of these variables. Instead, we choose a subset of these colors for a [theme palette](#theme-colors).
 
+Be sure to monitor contrast ratios as you customize colors. As shown below, we've added three contrast ratios to each of the main colors—one for the swatch's current colors, one for against white, and one for against black.

 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`) or dark (`#111`) contrast color based on the specified base color. This function is especially useful for mixins or loops where you're generating multiple classes.
