Created attachment 192792 [details] Example file from Writer Attached file contains some paragraphs which have paragraph background set to a not default color. When exported to PDF the PAC tool complains that there is not enough contrast between the text and the paragraph background. If the same file is saved as docx and exported to PDF with Word, then the PAC tool does not complain - indicating there is actually enough contrast, just the PDF tagging is slightly wrong somehow. 1. Open attached document 2. Export as PDF with tagging enabled (PDF UA or Create form or Archive is not necessary, but they don't make it disappear either) 3. Open it in the PAC tool ->under the WCAG category there is a warning about contrast not being large enough.
