Eau de Nile is one of those soft, slightly chalky greens that can swing either way depending on what you put next to it. Treat it as a warm green, not a cool mint, and it sings.
The golden rule: never put brilliant white near it. A stark white reads blue against Eau de Nile and drags the whole thing grey and grubby. Instead, run a creamy off-white on the skirting, architrave and ceiling. Farrow & Ball's Au Lait (LRV 80) is ideal — soft, milky and warm enough to flatter the green without competing. Paper III from Paint & Paper Library (LRV 75.3) does a similar job if you want something a shade quieter still. Both give you that crisp-but-soft frame Eau de Nile needs.
For contrast and grounding, reach for a warm brown. Mylands Cigar BH.20 (LRV 11.8) is a cracking partner — a rich, leathery tone that picks up the underlying warmth in the green and makes the scheme feel proper and considered rather than wishy-washy. Use it on a feature piece, a door, or pull it into the room via leather, oak furniture and antique brass hardware. That brass is doing a lot of the work, mind — it echoes the yellow buried in the green.
If you fancy a bolder accent, a dusky pink like Dulux Fuchsia Falls 2 (LRV 29.8) plays off Eau de Nile beautifully — green and pink are old friends, and this is a muted, grown-up version of that pairing rather than anything sugary. Keep it to cushions, a chair or an inside-cupboard moment.
Pull the yellow out further with soft ochre or stone-coloured textiles — linen curtains, a wool throw — and the room will feel layered and warm.
Practical tip: paint a big board in Eau de Nile, prop it against the wall and live with it across a full day. North-light will cool it; warm afternoon sun will bring the ochre up. Get the woodwork tone right first and the rest falls into place.
