Yes, and you've got a couple of cracking options. Dulux Viridian Tide (LRV 6.4) lands at ΔE 2 from Hague Blue — that's very close, well inside the threshold where the human eye stops noticing the difference once it's on the wall. For a fraction of the F&B price, it's the obvious pick if you just want that deep inky blue-green without the premium.
If eco credentials matter to you, COAT's The Drink (LRV 7.4) comes in at ΔE 2.8 — still a genuinely close match, and COAT is water-based, low-VOC and self-priming, so it's a doddle to live with. It reads a touch lighter than Hague Blue thanks to the slightly higher LRV, but in practice you're getting the same dark, moody character.
Crown Midnight Navy (LRV 6.6) is further out at ΔE 3.8 — noticeably different side by side, leaning more straight navy than Hague's teal-tinged depth. I'd only reach for it if the others aren't available to you.
Now, the honest bit: Hague Blue is one of those F&B colours where the depth comes partly from the pigment load and the way it shifts between green and blue depending on the light. Cheaper paints match the colour well, but the finish and that subtle chameleon quality can read slightly flatter. On a feature wall or joinery in a well-lit room you'll likely never notice. In a dim north-facing space where the colour does its dramatic best, the F&B version earns its keep a bit more.
My advice: order a sample pot of Viridian Tide and brush out a decent A4 patch — two coats — next to a Hague Blue sample. Live with it for a day across morning and evening light. Nine times out of ten you'll be perfectly happy with the cheaper option and the savings will fund the brushes.
