Luminous Blue for 2027: A Deeper Ocean Blue for Coastal Interiors

Some colors arrive as trends. Others feel more like recognition.

When WGSN and Coloro named Luminous Blue their 2027 Color of the Year—officially referenced as Coloro 125-28-38, a saturated blue that works especially well with warm wood, ivory, stone and soft gold—I was immediately drawn to it. This was not a color that felt unfamiliar to me. I started looking through my own artwork and realized how often I had already returned to this same family of ocean blues: sometimes cobalt, sometimes marine, sometimes almost electric.

It was there in the deeper passages of waves, in jellyfish, sea turtles and herons, and in the blue-and-gold pieces where I had used strong color simply because I loved what it did to the image.

Then we began placing some of those pieces into rooms inspired by Luminous Blue, and that was when the color became even more interesting. Against deeper blue walls, ivory looked brighter, walnut seemed richer, turquoise became more luminous and gold took on a beautiful warmth. The artwork did not disappear into all that blue; in many cases, it came alive in a completely different way.

That is what I want to explore here—not simply another Color of the Year announcement, but why a blue this vivid feels so natural in modern coastal interiors, how to use it without overwhelming a room, and why it works so beautifully with the colors and materials that already belong to the coast.

In April 2025, trend forecaster WGSN and color specialist Coloro announced Luminous Blue as their Color of the Year for 2027. Its official Coloro reference is 125-28-38. This is the WGSN × Coloro selection rather than an announcement from Pantone.

WGSN’s broader 2027 forecast explores ideas of interconnectedness—past and future, nature and technology, the familiar and the unexpected. Luminous Blue fits easily into that story. It has the depth and visual authority of an old-world pigment, but its intensity can also feel strikingly contemporary.

For interiors, that gives us a blue with far more presence than the hazy sea-glass colors often associated with coastal decorating. It is strong enough to shape the mood of a room, yet it can also make quieter materials—warm wood, ivory linen, natural stone and soft brass—look even more beautiful.

It is worth making one distinction here. Luminous Blue is a specific Coloro shade. The rooms and artwork in this article explore blues that share its spirit, from cobalt and marine blue to turquoise and deeper ocean tones, rather than claiming that every blue shown is an exact color match.

Coastal decorating has spent years favoring the softer side of blue: mist, faded sky, sea glass, weathered blue-gray and pale aqua. I still love those colors, but they represent only one part of what the coast actually gives us.

Spend enough time beside the water and blue becomes far more complicated. The shallows may be translucent turquoise or green. Farther out, the water deepens into cobalt and marine blue. Beneath clouds it can turn slate-colored, and under strong sun there are moments when the Gulf becomes so intensely blue it seems almost illuminated from within.

That is the side of coastal color that Luminous Blue brings forward. It has energy, but that does not mean a room using it has to feel loud. In fact, some of the most successful spaces we explored were remarkably calm because the stronger blue was balanced with natural wood, warm whites, stone and simple upholstery.

The lesson is not that every coastal room suddenly needs darker blue walls. It is that our idea of what qualifies as a coastal blue can become much more expansive.

Looking through my artwork after seeing Luminous Blue was unexpectedly exciting because I began noticing just how often variations of this color had already found their way into the work.

As an art student, I was fascinated by Katsushika Hokusai and the extraordinary movement in his waves. Later, as a graphic artist, I was drawn to Art Nouveau for many of the same reasons: flowing line, rhythm, movement and decorative detail. Those influences eventually found their way into my own interpretations of ocean life.

When I began creating waves, jellyfish, sea turtles and herons, I was not thinking about future color forecasts. I was choosing colors that felt right for the subject and that gave the image the energy I wanted. Deep blue, turquoise and gold became combinations I returned to because they reminded me of water and sunlight.

Seeing a color so close in spirit become part of the 2027 design conversation made me look at those pieces differently. It also made me curious about how these stronger blues could work in the rooms around them.

That is where this article really began.

There is one danger with any Color of the Year: once we begin seeing it everywhere, it is easy to feel as though the whole room needs to be redesigned around it. I would resist that impulse. If you already have a room you love, start by asking what a stronger blue could add rather than what it should replace. The answer might be one piece of blue coastal wall art, a velvet chair, painted cabinetry or a single saturated wall rather than an entirely blue room.

I would also avoid trying to match Luminous Blue exactly across every surface. The ocean certainly does not. Cobalt, marine blue, turquoise, blue-gray and deeper indigo tones can live beautifully together when the relationship between them feels intentional. In fact, some of the most interesting cobalt blue interior design comes from layering several blues rather than reproducing one shade over and over.

Blue and white will always have a place in coastal interiors, but introducing another natural element can make the combination far more interesting. Walnut, olive, limestone, brass or a small amount of mineral pink can add warmth and complexity without taking away from the blue.

There is no correct order for building a room around color. Sometimes you fall in love with the wall color first; other times the artwork provides the beginning of the palette, and everything else grows from what you notice inside it.

That is one reason this particular Luminous Blue interior design story became so interesting to me. When I began placing artwork I had already created into rooms with deeper blue walls, I could suddenly see relationships that had been there all along. Warm gold details became more luminous, walnut looked richer, pale aqua seemed brighter and the strongest blues in the artwork gained depth instead of disappearing into the wall.

The same idea works in a lighter room. Against warm white or ivory, a piece of saturated blue coastal wall art can carry nearly all of the room's stronger color. Add one related accent—a velvet chair, a pillow or a ceramic vessel—and the room begins to feel connected without becoming overly coordinated.

With glass art there is another layer as well. The glossy surface responds to natural light, so both the artwork and the room shift subtly throughout the day. That changing relationship feels especially appropriate for work inspired by water, because the sea never gives us exactly the same blue twice.

What I keep returning to is how natural this color feels once I stop thinking about it as the 2027 Color of the Year and begin thinking about where I have already seen it.

The coast has always contained versions of this blue—in deeper water, the underside of a wave, the blue-gray of a heron’s feathers, the translucent body of a jellyfish and those extraordinary moments when sunlight makes the ocean look almost electric. Depending on what surrounds it, the color can feel serene, dramatic, elegant or full of energy.

That is also why I think Luminous Blue for 2027 has more staying power in coastal interiors than a trend label might suggest. It works beautifully with materials that already belong naturally in these spaces: walnut and oak, limestone, woven fibers, ivory linen, soft gold and botanical greens. Even blue-and-gold coastal artwork, which can sound quite bold in theory, becomes surprisingly sophisticated when those colors are grounded by warm wood and quieter natural textures.

I loved these blues in my artwork long before they became part of a forecast, and seeing how beautifully the work responds to Luminous Blue-inspired rooms has only made me appreciate them more. The trend did not introduce me to the color; it made me look again at something I had already been drawn to.

If Luminous Blue reminds you of water you love, a place you remember or a piece of art that makes you stop for a moment, that connection matters more than whether the color is fashionable this year. A trend may give us permission to notice a color, but what makes it last in our homes is the meaning we attach to it.

One of the easiest ways to bring a stronger ocean blue into a room is through artwork. It allows the color to have real presence without asking the entire space to revolve around it, and it can introduce several related blues—cobalt, turquoise, marine blue and sea-glass tones—at once.

The pieces below are some of the works that made this Luminous Blue story feel so exciting to me. Each carries a different expression of blue, from flowing water and sea life to gold-lined waves and coastal birds, and each shows how naturally this color family already lives within the world of Echoes of the Sea.
