The Unicolour range is a made-to-measure vertical blind collection from Blinds By Post, covering 26 finishes from £10.44. What distinguishes it from a single-width range is the dual vane offering: a number of colours are available in both standard 89mm and wider 127mm formats, letting you choose the visual weight of the vane to suit your window size and room proportions.

Who it suits

Vertical blinds are the natural choice for wide openings - patio doors, conservatory windows, and large picture windows - where the fabric slides along a track rather than rolling up. The Unicolour range works well in these settings across most rooms.

For living rooms and home offices, the light-filtering and dimout characteristics of vertical fabrics provide good privacy without cutting out all daylight when the vanes are partially rotated. For bedrooms, the opacity of specific Unicolour fabrics is not detailed at range level, so if blackout performance matters - for shift workers or rooms that need genuine darkness - you should confirm the opacity of your chosen colour directly with Blinds By Post before ordering.

The range is available across beige, black, blue, brown, cream, green, grey, purple, and red tonal groups, which makes it a broad functional choice rather than a specialist one. The structured look of vertical vanes suits contemporary and open-plan spaces; traditional or cosier interiors often read better with roman or roller styles.

The colours

26 colours available

The 26 finishes in this range cover a range from quiet to considered. Neutrals make up the bulk: Taupe, Flint, Dove, Shell, Beige, and Charcoal sit in the mid-ground between white and grey. At the lighter end, White (127mm) keeps things simple. Deeper tones include Navy, Lapis (available in both widths), Morello, and Mulberry, giving genuine depth to the darker end of the palette. Cyan and Glade introduce cooler, fresher options for rooms that suit a lighter touch of colour.

Several finishes are available in both the standard and 127mm width - Kara, Lapis, Flint, Taupe, Dove, and Shell appear in both formats. The wider vane gives a less busy appearance across a large window, and some people prefer the cleaner horizontal rhythm when the vanes hang across a patio door. Where a finish is listed only in 127mm, that indicates the wider format is the sole option for that colour.

Price by your dimensions

Made to measure from £10.44. Check Blinds By Post for the price at your exact window size.

With a from-price of £10.44, the Unicolour range sits in the mid-range of Blinds By Post's vertical blind offering - slightly above entry-level but not in the same bracket as more specialist or heavily textured fabrics. Made-to-measure pricing scales with the width and drop of your window, so measure carefully before ordering.

How it compares

The dual vane width is a practical differentiator. Many vertical ranges offer only a single vane width; having both 89mm and 127mm available in the same palette means you can match the vane scale to your window without switching to a different product family.

If you need confirmed blackout performance across the whole range, some vertical ranges at other retailers explicitly label each vane as blackout or fire-retardant blackout - that transparency is useful when light control is the main brief. Unicolour does not offer that level of opacity detail at range level, so if it matters for your room, contact Blinds By Post with your specific finish choice before ordering.

If you are comparing Unicolour against other Blinds By Post vertical ranges, Unishade and Splash offer overlapping colour selections with the same dual-width structure. Unicolour's advantage is simply its wider palette: 26 finishes gives you more scope to find something that works with your existing room colour without compromising on vane width. For insulation, no vertical blind offers meaningful thermal performance - a cellular or honeycomb blind is the right tool for that job, particularly for conservatory windows or poorly-insulated glazing.
