Blue is one of the easiest colours to live with at a window, and a Roman blind is one of the softest ways to wear it. Where a roller lays the colour flat and a venetian breaks it into slats, a Roman gathers its fabric into folds as it lifts, so the shade reads as soft furnishing rather than a coated panel. That suits the calm, restful quality people reach for when they choose blue in the first place. This guide is for anyone who has decided on blue and on a Roman, and now wants to know which shade, which fabric and which retailer. It spans a patterned designer range, a value plain and a mid plain option, drawn from three different UK retailers.
What blue brings to a room
Blue is the quiet end of the colour wheel. It is the shade most often described as calm and restful, which is why it lands so naturally in bedrooms and bathrooms - rooms where you want the eye to settle rather than be drawn. It also carries a coastal association that a kitchen or a garden-facing room can lean into without tipping over into theme. A Roman in blue gives you that mood with a soft, dressed finish rather than a hard flat one.
The breadth of blue is what makes it worth thinking about by shade. A pale duck egg is barely a colour at all - it works almost as a soft neutral, lifting a white scheme without competing with it. Move through delphinium and sky into denim, and the blue starts to carry the room rather than support it. At the deep end, Prussian blue and navy are close to a dark statement, reading as confident and enclosing in the way a charcoal would, but with a softer, less austere note.
Light and aspect change how a blue behaves. A north-facing room takes the cooler, cleaner blues further towards grey, which can feel crisp or can feel chilly depending on what else is in the room - warm woods and brass pull it back. A south-facing room floods a pale blue with warmth and keeps even a deeper shade from feeling cold. As a rough rule, the cooler and paler the blue, the more it cools a room; the deeper or greyer-warm the blue, the more it holds its own against strong light. Test a swatch against your own wall and aspect before committing, because the same shade can read quite differently across two rooms in the same house.
What to look for
Fabric and lining. A Roman is made from furnishing-weight fabric, and the choice between a print and a plain is the first decision. A patterned blue makes the window a feature; a plain blue makes it a soft backdrop for colour coming from elsewhere. Most Roman ranges offer a lining option, which adds weight, improves the drape and increases opacity. A textured plain such as a faux suede sits between the two, reading as more considered than a flat plain without the commitment of a print.
Blackout vs light-filtering. A Roman's standard lining filters light rather than blocking it, which suits a living room or a kitchen. For a bedroom, look for a blackout lining as an order option on the fabric you have chosen - it is usually an upgrade on the same blind rather than a separate product. Treat the retailer's blackout description as their claim rather than a guarantee, and combine it with a face-fix fit if true darkness matters.
Chain side. Roman blinds raise on a cord or chain, and most retailers let you choose which side it sits. Pick the side that suits the room's traffic and any neighbouring blind, and in a child's room choose a cord-safe option in line with UK requirements for domestic blinds.
Recess vs exterior fit. A blind fitted inside the recess looks neat but leaves the window's reveal visible and a small gap each side. An exterior, face-fix mount sits on the wall above the window and overhangs the recess, which gives a tighter light seal and makes a short window look taller. For a bedroom blue where you want darkness, face-fix is usually the better choice.
Stacking. A Roman gathers into a stack of pleats at the top of the window when raised, so it always covers a band of glass even when fully up. On a tall window this is invisible; on a short one it costs daylight. Measure how much glass you are willing to lose, and remember a lined blue fabric stacks a little deeper than an unlined one.
How we chose
We wanted three honest routes into a blue Roman rather than three versions of the same blind, so each pick answers a different brief and comes from a different retailer.
The first is the patterned designer route: a licensed range with the widest spread of blue prints, for the buyer who wants the window to be the feature. The second is the value plain route: a textured plain at a lower entry price, for the buyer who wants a soft blue backdrop without a designer premium. The third is a mid plain option, a clean plain blue from a third retailer, sitting between the two on price and giving an alternative source if the value pick's shades do not land. Across the three you get pattern and plain, a range of blue shades from pale to deep, and three suppliers to compare on price and fit options.

Pick details
Laura Ashley Roman Blinds
at Blinds By Post
Laura Ashley designs across duck egg, delphinium and seaspray blues.
When the blue is meant to be the feature, the Laura Ashley Roman range at Blinds By Post is our pick for pattern. This is the designer route, drawing on the Laura Ashley archive of florals and stripes, and it carries the widest patterned blue choice of anything in this guide. The blues run across named shades such as Duck Egg, Delphinium and Seaspray, so you can stay soft and coastal with a duck egg floral or go cleaner and brighter with a delphinium.
It sits at a mid entry price, above the value plain below but earning it through the licensed prints and the soft fold a Roman gives a detailed design. A print needs a window wide enough to show a full motif, so it flatters a wider living room or bedroom window more than a narrow one. Worth knowing for comparison: the same Laura Ashley Roman line is also stocked at Swift Direct Blinds, so if you want to check fit options or pricing against a second retailer, you can see the identical range there before deciding.
Florence Faux Suede Roman Blinds
at 247 Blinds
A faux-suede Roman in cloud, ink and Prussian blue at a lower entry price.
For a plain blue without a designer premium, the Florence Faux Suede Roman at 247 Blinds is our value pick. It is the budget-conscious plain route, and the faux-suede fabric is what lifts it above a flat plain - a soft matte nap that catches the light gently and reads as more considered than an ordinary plain weave. That texture does a lot of the work in a calm, quiet room where you do not want a print.
The blues cover Cloud Blue, Ink Blue and Prussian Blue, which neatly spans the range: Cloud Blue for a pale, restful backdrop, Ink Blue for a stronger mid tone, and Prussian Blue for the deep, enclosing end that suits a bedroom or a dressed living room. It carries a lower entry price than the designer pick, which makes it the sensible choice if you are dressing several windows or want the soft blue mood at a controlled cost. As a plain, it works best where the pattern in the room is coming from elsewhere - a rug, a wallpaper, the bedding - and the window is meant to settle the scheme rather than lead it.
Solo Roman Blinds
at English Blinds
A plain Roman in sky and denim blue from English Blinds.
The Solo Roman at English Blinds is our mid plain pick, and the alternative source if the value pick's shades do not suit. It is a clean plain blue rather than a textured or patterned one, which makes it the most straightforward of the three - a flat, calm panel of colour that folds softly as it lifts. That simplicity is the point: where the faux suede adds nap and the Laura Ashley range adds print, the Solo lets the blue speak plainly.
It comes in Sky and Denim, two shades that bracket the everyday middle of blue. Sky is the lighter, fresher option, suited to a bright bedroom or a coastal-leaning room; Denim is the deeper, more grounded tone that carries a living room or a study without going as dark as a Prussian or navy. It sits at a mid entry price, between the value plain and the designer range, so it is the pick when you want a plain blue Roman from a third retailer, a cleaner finish than the faux suede, and a price that lands in the middle. Check a swatch against your light, since a plain blue shows aspect more honestly than a textured one.
What we didn't include
We have kept this guide to blue, and to the choice between a patterned designer Roman and two plains. A note on the gaps.
We have not covered other colours here. Greens, greys, neutrals and the warmer end of the palette each have their own demands at a window, and they have their own guides rather than being squeezed in alongside blue. If you are still deciding on colour, those are the place to compare.
We have also not treated blackout as a separate pick. A blackout lining on a Roman is an order option on the fabric you choose rather than a different product, so we have folded it into the buying advice above rather than listing a dedicated blackout blue. If a bedroom needs genuine darkness, ask about a blackout lining on whichever of these blues you prefer, and pair it with a face-fix fit for the tightest seal.
