WCAG 2.0 uses the same three levels of conformance (A, AA, AAA) as WCAG 1.0, but has redefined them. The WCAG working group maintains an extensive list of web accessibility techniques and common failure cases for WCAG 2.0. [24] WCAG 2.1 is backwards-compatible with WCAG 2.0, which it extends with a further 17 success criteria.

Several tools are based on WCAG 1.0's algorithm, while the reference is now WCAG 2.0's algorithm. If the tool doesn't specifically mention that it is based on WCAG 2.0, assume that it is outdated. The Wikimedia Foundation Design team has provided a color palette with colors being marked toward level AA conformance. It is used for all user ...
The Template:Color contrast conformance gives a "AAA", "AA" or "none" judgment for the level of conformance to WCAG 2.0 of two colors together, in terms of contrast ratio, where the colors can be either RGB #numbers (#56F3BB) or color names (green, darkorange, or NavahoWhite, etc.).
[1] [4] Each member country is responsible for implementing national legislation that conforms. [5] [6] A minimum level of harmonization is required which Member States must maintain. National legislation can exceed these minimum requirements, and some countries have chosen to do so.
