Cool colors that create calm: how to use blue and green in the home
Cool colors are the home’s pause button. The right shades of blue, green, and cool gray can slow down the pace, soften the impression, and make the room more restful—without becoming sterile or cold. At Artiley, we work with color temperature in wall art every day, and time and time again we see how small adjustments in color, light, and material make a huge difference. Below, we share our most useful lessons and concrete advice for achieving that long-awaited, relaxed atmosphere.
What do cool colors mean – and why are they calming?
Blue and green are classic “cool” colors, but their undertones are just as important. A gray wall with blue undertones feels cooler than a greige with a beige base. Psychologically, cool colors are associated with water, shadow, and distance – elements that feel calm and spacious. In practice, this means that cool colors reduce visual noise and give the eye longer pauses between different elements of the interior.
Balance first, accents later
Start from the whole you already have. Let the fabric of the sofa, the texture of the rug and the color of the walls control how much coolness you add. A good way to work is to use a cool base (wall or larger textiles), follow up with soft intermediate layers (pillows, throws) and round off with a unified accent in the form of a canvas painting. The point is not to build the entire room around a painting, but to let the artwork reinforce the mood you are looking for.
An example is our Ocean's Whisper painting. With its shades of blue and white, it creates a calm, seaside feel that works in both bedrooms and living rooms. We usually recommend that the width of the painting be around two-thirds of the furniture underneath, and that the center of the motif be approximately at eye level – often around 145 cm from the floor – as a starting point to adjust from according to the room and the light.
The role of light: from icy cold to inviting
Cool colors require thoughtful lighting to be harmonious rather than clinical. Daylight from the north enhances the coolness – beautiful, but sometimes austere. A warm-toned LED (2700–3000K), textile shades and indirect light round off the edges and make blue and green more embracing. In our stylings we also see that matte or lightly textured wall art, like many of our canvas prints, reduces glare and gives a softer expression.
Room by room: how to make colors work together
Bedroom: Choose muted blue-gray or misty blue shades and combine with natural materials – linen, light oak, wool. Drape the bed with a neutral bedspread base and add two or three pillows in cool tones. A calm ocean scene like Ocean's Whisper above the headboard is often perceived as calming without being overpowering.
Living room: Work with layers. A cool wall, a crisp blue-striped pillow, a gray-green throw – and a larger abstract painting that ties the scale together. To keep the room warm enough, you can add small touches of beige, sand or brass; cool colors become extra beautiful when they meet soft neutral tones.

Office: Cool greens (think sage green) can bring focus and mental peace. Abstract wall art with a clear horizon line creates a visual break in screen-heavy environments.
Hallway: Narrow walls look good with vertical motifs or a small-format triptych. Keep the color scheme consistent – the hallway should catch the eye, not set off fireworks.
Color matching and materials
The most common tip we give is to compare “temperature” more than exact shade. A steel blue cushion and a misty blue canvas painting may be different in NCS code, but feel harmonious if both have a cool undertone. Textures make as much of a difference as color: coarse linen, matte ceramics and brushed metals carry cool colors better than high-gloss plastic. Therefore, let the surface of the wall art – often matte in the case of canvas paintings – become a co-player to dampen sharp reflections.
Quick, practical advice
- Start small: Try a cool throw or poster before investing in a large painting.
- Work in monochrome: Three shades of the same blue often provide more calm than three completely different colors.
- Center of gravity: Keep the darkest cool tone lower in the room (carpet, lower storage) and the lighter ones higher up (wall, curtain, art).
- Light balance: Complement cold walls with warm lighting and vice versa for an even temperature.
- Size of art: On a wide wall, a larger canvas feels more harmonious than many small ones that create visual noise.
The role of art in the cool palette
Cool colors work best when they create rhythm, not dominance. A well-chosen canvas can be just that rhythm – a calm horizon, a soft blue transition, a light green tone that recurs in a side table or vase. We see from our customers that it is the interplay between color, light and material that lowers the pulse, not a single color code. So think of the wall art as a voice in the choir, not a soloist – and let the room breathe.
