When changing the Background colours of the TAble Block, the commands are there, but the colours are not updated neither in the preview nor in the live page / post

See Snip or example at https://release.k8s.p4.greenpeace.org/international/luca-table-tests/

TASKS:

• Make sure the selected Background colours (Subtle Pale Green, Blue, Pink) render collectly in both preview and live page / post
• Align with wmorrisj to get the right colour codes for each
• Clarify with wmorrisj if the Heading row should remain blue (I don't think so) for the other backround colours or (if not) get the right colour codes for each and implement
• Update the Handbook page with all colour codes - https://planet4.greenpeace.org/handbook/block-spreadsheet-table/
