What’s broken?

This issue was identified during the Docs accessibility audit on a page containing table-related content.

Audited page:
https://docs.numerique.gouv.fr/docs/0d998bef-1b69-47ce-bd18-83d4d849c734/

Some color combinations used inside BlockNote tables do not provide enough contrast.

Examples found during the audit:

  • #E03E3E on #DDEDEA - contrast ratio: 3.53
  • #E03E3E on #FFFFFF - contrast ratio: 4.26

For normal text, the minimum expected contrast ratio is 4.5:1.

These combinations can make the content difficult to read for users with low vision or color perception difficulties.

Users with low vision may have difficulty reading the table content.

BlockNote version

0.51.4

What did you expect to happen?

Text colors used inside tables should meet the minimum contrast requirements.

For normal text, the contrast ratio should be at least 4.5:1.

The table color palette should prevent or avoid combinations that produce insufficient contrast.

Steps to reproduce

Insert a table using BlockNote.
Apply table/text colors using the available color options.
Check the contrast ratio for the following combinations:

  • #E03E3E on #DDEDEA
  • #E03E3E on #FFFFFF
    Notice that the contrast ratio is below 4.5:1.
BlockNote version

0.51.4

Additional context

This can also affect users in bright environments or users with color perception difficulties.

WCAG Criteria

WCAG 1.4.3, Contrast (Minimum)
