Revere Pewter is one of Benjamin Moore's all-time greats — a warm, greige neutral that reads as a soft taupe in most rooms and behaves itself in almost any light. The good news is Dulux gets you very close indeed.
Dulux Shaded Stone is your best bet, at ΔE 1.6 from the original with an LRV of 55.6. Anything under ΔE 2.5 is what I'd call a very close match — you'd be hard pushed to spot the difference on a wall, and certainly not once the furniture's in and the light's moving across it through the day.
If you want to hedge slightly warmer, Dulux Crispy Crumble sits at ΔE 1.9 with an LRV of 56.4. Practically the same brightness, just a touch more biscuit to it. Both are bang in the same greige territory as Revere Pewter, and both sit comfortably above LRV 55, so they'll keep a room feeling light without tipping into stark.
The "but what about" here is always undertone. Revere Pewter has a green-grey ghost in it that shows up in north light — it's part of what makes it so liveable. Shaded Stone tracks that undertone faithfully, which is exactly why it's the tighter match. Crispy Crumble leans marginally warmer, so in a properly cool north-facing room it'll feel a hair cosier. Neither will go pink or yellow on you, which is the usual trap with greige.
Practical advice: don't trust the colour-card chip. Get sample pots of both Shaded Stone and Crispy Crumble, paint two coats onto an A2 sheet of lining paper, and move them around the room over a full day. Greige is the most light-dependent family there is — the maths gets you to within ΔE 1.6, but your own walls make the final call. Once you've watched them at 8am and again at dusk, you'll know which one's right for the room.
