Importance: High

Call For Consensus - ends Monday May 17th at noon Boston time.

The Working Group has discussed a change to the color contrast formula to update the dated reference to an old spec. It includes a note saying that it won't affect the values generated from the formula. This change would add an errata to WCAG 2.0 & 2.1, and be included in 2.2.

The specific changes are detailed in this pull request:<>

If you have concerns about this proposed consensus position that have not been discussed already and feel that those concerns result in you "not being able to live with" this decision, please let the group know before the CfC deadline.

Kind regards,
