Why do velvet curtains look different colours from different angles?
Updated
Velvet looks like different colours because its surface is a pile of tiny fibres that lean one way. They reflect light differently depending on where the light comes from and where you stand, so the shade changes with the angle, the light and the direction of the pile. It is a normal feature of velvet, not a dye fault.
Velvet has a short, dense pile of upright fibres. The fibres lean slightly in one direction, called the lie of the pile. The fibres reflect light differently depending on where the light comes from and where you stand. That is why velvet seems to change colour as you move.
What changes the shade
- Viewing angle. Looking along the pile and against it gives a different depth of colour.
- Light. A window, a lamp and daylight at different times each show the pile differently.
- Pile direction. If neighbouring pieces of fabric are cut with the pile running different ways, they can look like two shades.
- Crushing. Where the pile is pressed flat, it reflects light differently and shows as a lighter or darker patch.
Handling and care
Hands can crush the pile. Open and close velvet curtains with a wand or by the leading edge rather than by gripping the fabric. Do not use steam, heat or a cleaning product on velvet before you check the care instructions, because some velvets mark. For stubborn marks ask a professional curtain cleaner.
Pile direction in curtains
Fabric makers do not all agree on which way to hang the pile. Some recommend pile facing up, which gives a deeper colour. Others recommend pile running down, for a smooth hang and even shading. What matters is that every panel on a window is cut and hung the same way, so the colour matches across the curtain.
| Point | Why it matters |
|---|---|
| Pile direction on every panel | Prevents two shades side by side |
| Lining | Adds body and protects the face fabric |
| Weight and drop | Heavy velvets settle further after hanging |
| Floor clearance | Agree extra clearance for a heavy fabric |
| Pre training | Not available for velvet |
Velvet is often a heavy fabric, and heavy fabrics stretch and settle more than light ones. Look at a large sample in your own room at different times of day before you choose. Your curtain retailer can show you one and explain how it will hang. Speedy Blinds makes curtains for retailers.
Other ways people ask this
Why does velvet look lighter in some places?
The pile lies in different directions or has been pressed flat, so it reflects light differently.
Is velvet changing colour a fault?
A colour change with angle and light is not a fault. It is how a pile fabric reflects light.
How do I stop velvet curtains getting marks?
Avoid pressing or gripping the pile. Use a wand, and check the care instructions.
Does the pile direction matter for curtains?
Yes. Every panel should be cut and hung with the pile running the same way.
