As of now Base10 `#222` in combination with Accent50 `#36c` fails WCAG 2.0 level AA slightly by providing [[ https://webaim.org/resources/contrastchecker/ | 2.96:1 contrast ]].
While amending Accent50 seems not only problematic from a branding & visual disruption perspective, Base10 is //currently the only base that doesn't follow the blue tint logic// and would be relatively easy to amend.
Proposing therefore changing Base10 from `#222` to `#202122` to reach required [[ https://www.w3.org/TR/2008/NOTE-WCAG20-TECHS-20081211/G183 | 3:1 contrast ratio ]].

== Proposal and Process
[x] Agree on color amendment – agreed on in Design Style Guide meeting of 2020-04-07
[x] Rollout to
[x] [[ https://github.com/wikimedia/WikimediaUI-Style-Guide/pull/364/files | Style Guide ]],
[x] WikimediaUI Base and
[x] OOUI in same release cycle
[ ] Slowly rolling out to further [[ https://codesearch.wmflabs.org/deployed/?q=%23222&i=nope&files=&repos= | code occurrences as well ]]
Note, Wikimedia deployed Translate extension is excluded from color updates, as it's completely out of sync from UI pattern perspective and single color updates would just side-track extension.
