Your passport doesn’t matter. What matters is where you were for the past 14 (maybe 10) days.
France is currently open to UK residents who are vaccinated. No test needed. But things change quickly. This page is kept updated and you can receive email notification of changes.

AND currently you have to quarantine on return from France! That is the UK government decision.
From that page:
The UK is currently on the French
amber list. Entry requirements are different depending on whether you are fully vaccinated or not.
Travellers who are fully vaccinated do not need an essential reason to travel to France and do not need to self-isolate on arrival. From 18 July,
fully vaccinated adults no longer need to present evidence of a negative test result before travel. Fully vaccinated travellers will need to present the following documents:
- a completed ‘sworn statement’ (déclaration sur l’honneur) form self-certifying they are not suffering from symptoms associated with coronavirus and have not been in contact with confirmed cases in the preceding fortnight. This can be found on the French government’s website
- proof of vaccination status
Demonstrating your COVID-19 vaccination status
France will accept the UK’s solutions, including both digital and paper certification, to
demonstrate your COVID vaccination status at the border.
Travel from France to the UK
If you intend to travel to
England,
Scotland, or
Wales, including UK nationals returning home from travel abroad, you must provide evidence of a negative COVID-19 test result, taken up to 3 days before departure. If you do not comply (and you do not have a valid exemption) your airline or carrier may refuse you boarding and/or you may be fined on arrival. You can access tests in France via the
French government’s website. Travellers will then be subject to
quarantine measures in place in the UK upon entry.

It is so confusing and changes so often that I lose track.
