Created attachment 198016 [details] Sample doc Originally reported on the accessibility mailing list [1]: >Hi, with build: >https://git.libreoffice.org/core/+log/65412f067af443213e726c93f137ccc85c9a1e06 > >I see that colour contrast checker don't apply correctly WCAG 1.4.3. If i >set a color with large-scale text (14pt bold and more or 18pt and more >Normal) contrast ratio is 3:1 instead of 4,5:1 applied. Steps to reproduce: 1) open attached sample doc in Writer 2) check the accessibility check sidebar Actual results: Errors about too low contrast are shown. Expected result: No errors should be shown, because the contrast ratio is larger than 3.0, which is sufficient for large text according to the WCAG spec: https://www.w3.org/WAI/WCAG22/Understanding/contrast-minimum.html [1] https://listarchives.libreoffice.org/global/accessibility/msg01204.html
