Colour Drenching: Let's investigate this single shade trend

Kya deLongchamps champions her five drenching paint favourites, with tips to make this technique work.

Wimborne White by Farrow & Ball, From €26 per litre in Estate Emulsion, paintonline.ie.

Colour drenching continues to excite and inspire for autumn/winter 2026, so let’s investigate five trending possibilities to dress up that entire room in a single shade. While ‘life should be lived like the blazes’ (Jilly Cooper) and it is just paint — splash a very dark colour all over the ceiling — you must be prepared to use several layers of undercoat to wave it goodbye.

White horses

To run with the interior designers, it’s white all the way. White is not aesthetic cowardice. It’s a statement choice, because it is so highly present. Even stirred with an exquisite little undertone towards a warmer, off-white, white retains unique talents. Taking white from the skirting to the skylight might not be revolutionary, but it always works. White hurls shadow out of corners, flicks light out of imperfections in plasterwork, and throws back the ceiling and walls. Singing with the aspect and architecture, it shows different tonal play and intensities, depending on surrounding furnishings and the light falling on the surface. Chill? Pale blues and white are not cold; thermally cold rooms are cold. Include plenty of texture and warm colour in accessorising, flooring, warm Kelvin counts (lighting) to build up visual comfort, and character. My choice for autumn/winter 2026 would be the highly popular Farrow & Ball, Wimborne White (No. 239), which has a raw, plaster charm with a warm, yellow pigment. F&B suggest complementing Wimborne White with All White (No. 2005), with its colder, blue undertones and no pigment additions; and with full-on colours, like St Giles Blue, a gentle nautical often used to accent the back of bookshelves.

Divine Damson

Going deeper, we’ve all noticed a rich, red brown trotting down the fashion runways and swinging off the clothes rails this year. Divine Damson, by Graham and Brown, is their daring 2026 colour of the year. Figgy, fruity, decadent, but reassuring, it’s like dating someone you’ve deemed just too sophisticated to take seriously, only to discover they are actually gentle-hearted spouse material. Graham and Browne explain that the drying process for this opulent purple is key. It may appear overly bright in the first hours of application, but wait and it will reveal its elegant, calming depth and quality. G&B suggest their powdery, soft, yellow Wild Rye, and powder blues for accents against Divine Damson, and this leads on to pale or middling-coloured timber, which sits up beautifully against a velvet, dark cloak of its delicious plum presence. The brand also offers a range of mythologically inspired custom mural wallpapers.

Divine Damson, Graham & Brown, in Ultra Resistance Matt from €48 per litre, grahambrown.com/ie.

One of their latest, Eternal Weave (a paisley inhabited by various butterflies, moths, and fantasy lizards), contains licks of Divine Damson in two colourways. If you love Divine Damson, but want something a touch earthier, investigate Graham & Brown Witches Bru in an ultra-flat matt. From €48 per litre; murals €250 for a two-roll set, grahambrown.com/ie.

Blue (still swinging)

Dulux took us all by surprise by electing for not one, but three blues for 2026 — and they are all stunners. Blue has endured over the last five to eight years in every tone from icy to ink. Slow Swing is my Dulux champion, as it’s such a confident contemporary and sits so naturally with familiar new neutrals, including rain-greys, silvers, and various blue-based whites. It’s versatile in harmonising with aubergines, umbers, cobalt, and even lilac shades. It’s so tempting to break this blue down in to blue-and-white walls and features, and it’s a gorgeous contender for a bathroom in need of some soul. No one will judge you for using at least one other tone when covering a room in character colour, so test and test again to ensure the final effect is relaxed rather than oppressive.

Slow Swing. 750ml Heritage Eggshell, €32, Heritage Velvet (washable) Matt from €20 per litre, all Dulux suppliers.

When drenching in this or any deep colour, try to keep the finish the same over all the surfacing and materials (plaster and woodwork) — ultra matt if you want to be completely on-trend. Backing up some dimensional decorating, one texture gifts the space that coherent, considered look we all crave in a monochrome masterpiece. 750ml Heritage Eggshell, €32, Heritage Velvet (washable) matt from €20 per litre; various suppliers.

Shake out the spice

Autumn is a time of perennial spice, and powdery cinnamon is one of my favourites in an all-over room colour. If you’re attracted to the fashionable, sugar-almond pinks, but are looking for something a little more grounded, cinnamon could be just the touch of flavour you need. It’s a little golden, it’s a little brown, it has a touch of Mediterranean juice to it — there’s a lot of storytelling on offer. Stick with a classic, terracotta-inclined shade or investigate new cinnamon inspirations, including Benjamin Moore’s Cinnamon Slate (2113-40), a really interesting combination of heathered plum and velvety brown in a highly modern colour that leaves boring mid-greys in the rear-view mirror (close to Little Greene Adventurer). Classic cinnamon, like Little Greene Taos House, is particularly beautiful used in the kitchen (well, it’s a perfect ingredient there), forming a delicious backdrop to an accrued, free-standing timber kitchen or sleek built-ins and accent notes in white, creams, cloud grey, sages, beiges, and soft blues.

Taos House by Fired Earth. Wipeable Matt Emulsion, from €26 per litre. Suppliers include stillorgandecor.ie (Cork).

Its organic honesty will agree with weathered metals, raw wood, hand-made weaves, and red brick. Benjamin Moore’s Cinnamon (2174-20) comes in ‘digital-dollop’ samples, but always test on site with actual paint. PC screens and phone renderings are never reliable. For a library or hall where you want to go a little redder, Rich Chestnut (2920-20) is a heritage russet destined to marry with limestone flags. A huge range of finishes from €22 per litre (Aura are the most expensive and pigment rich). Benjamin Moore suppliers include thepaintstore.ie (Cork).

Pink obsessions

I was tempted to face you all towards Freckle, a stunning, golden yellow, that’s Earthborn’s colour of the year, but during the course of this feature I became completely obsessed with the brand’s new Thimble Lane pink.

This could be a visual hangover from the weird loveliness that was Margo Robbie’s ‘skin’ bedroom in Wuthering Heights. Both colours are deeply romantic and on the paler side of colour drench choices. The pull to Thimble Lane became so strong, I slathered it all over a tiny, Marie Antoinette-inclined cloakroom I’m conjuring for a friend. Described as ‘blush-pink with a thimbleful of yellow’, Thimble Pink comes in Earthborn’s celebrated clay paint that’s not only gorgeous, but ultra eco-friendly, breathable, and virtually VOC free. It’s creamy, highly opaque, and covers the surface in two coats reliably with no nasty odours during application or curing.

Earthborn Thimble Lane Pink (Clay-Paint). From €29 per litre, suppliers include Pat McDonnell Paints (Cork) and conservationtech.ie.

Pink can be a bit mumsy and unsettling to those who don’t like it even in these powdery colours. Check with the whole family before using it in a drench in a communal room. You can dial back the sugar high with complementary colours, including greys, greens (olives and sage), and many blues, including a rubbed blue/black. Like Farrow & Ball’s Setting Plaster (more yellow again), Thimble Lane is a pretty tonal backdrop for cream linen and boucle upholstered furniture. €28 per litre, suppliers include Pat McDonnell Paints and conservationtech.ie.
