This template checks for compliance with WCAG G17, i.e. that a background–foreground colour combination has got a contrast ratio of more than 7:1. It takes two arguments, the base colour value, and the tracking category, category , to place non-compliant transclusions in.
This template determines the pair of colors with the larger contrast ratio: color1/color2 or color1/color3. This is useful for selecting a foreground/background color pair. For accessibility, WCAG 2.0 AA guidelines require a contrast ratio of 3 or larger for large text, and 4.5 or larger for normal sized text.
This template checks for compliance with WCAG G17, i.e. that a background–foreground colour combination has got a contrast ratio of more than 4.5:1.It takes two arguments, the base colour value, and the tracking category, category, to place non-compliant transclusions in.
An LCD technology is dynamic contrast (DC), also called advanced contrast ratio (ACR), and smart contrast ratio (SCR [4]) and various other designations.When there is a need to display a dark image, a display that supports dynamic contrast underpowers the backlight lamp (or decreases the aperture of the projector's lens using an iris), but proportionately amplifies the transmission through the ...

This ratio, often called contrast ratio, CR, (actually being a luminance ratio), is often used for high luminances and for specification of the contrast of electronic visual display devices. The luminance contrast (ratio), CR, is a dimensionless number , often indicated by adding ":1" to the value of the quotient (e.g. CR = 900:1).
