Sun Fading: Where Not to Hang Art

October 18, 2026

Take down a picture that has hung in a sunny room for ten years, and you may find a brighter rectangle of wallpaper behind it. The wall has faded round the picture. The picture has been fading too. You don't notice, because it happens slowly and all over.

Light damages everything it falls on: fabric, wood, paint, paper and ink. It can't be reversed. It can be slowed a great deal by choosing the right wall.

Why light fades colour

Colour comes from molecules in ink and dye that absorb some light and reflect the rest. Light is energy. Over time it breaks those molecules apart. Once broken, they no longer hold their colour.

Ultraviolet light does the most harm. It is invisible, and sunlight is full of it.
Visible light also fades colour, more slowly. Blocking UV helps a lot, and it doesn't stop fading entirely.
Heat from sunlight speeds up the chemistry and dries materials out.

The damage adds up. A little light for a long time does the same as strong light for a short time. Every hour counts, and none of it comes back.

The risky places

A wall the sun falls on directly. This is the one to avoid. If a patch of sunlight crosses the picture at any time of day, it is in the wrong place.
Opposite a south-facing or west-facing window, in the northern hemisphere. South windows get sun for most of the day. West windows get the low, strong sun of the afternoon and evening.
Beside a window, where the sun rakes along the wall.
Under a skylight.
A conservatory, sunroom or glazed porch. The worst room in the house for art.
Near glass doors.
Opposite a mirror or a white wall that bounces sun.

Remember the seasons. The winter sun is lower and reaches deeper into a room than the summer sun. A wall that is shaded in June may be in full sun in December.

The safer places

The wall the window is in. Sun comes through the window and falls on the far side of the room. The wall round the window stays in shade.
Rooms with north-facing windows, in the northern hemisphere. They get soft, indirect light all day. Artists have always preferred a north-lit studio.
Hallways, landings and stairwells with no direct sun.
Any wall the sun never touches.

The one-day test

On a sunny day, look at the wall you have in mind in the morning, at noon, in mid-afternoon and in the evening. Take a photograph each time. If sunlight never falls on it, the wall is fine. If it does, note when and for how long. Ten minutes of weak morning sun is a small matter. Three hours of afternoon sun is not.

Which colours fade first

Yellows and reds are usually the least stable. Magenta and pink often go early as well.
Blues and blacks tend to last longer.

So a faded print doesn't only get paler. It shifts. As the warm colours fade, the picture turns bluer and cooler. Skin tones go grey. Sunsets lose their fire. In neon art, the hot pinks and oranges are the colours at risk.

Dark, saturated pictures also show fading more plainly than pale ones, because they have more to lose.

How different materials cope

Inks. Pigment inks resist light far better than dye inks. Quality prints are made to last many years in normal indoor light. No ink is proof against direct sun. See what is a giclée print.
Canvas. It has no glass over it, so nothing filters the light. It also has no glass to trap heat. See what archival means on a canvas.
Posters. Paper can yellow and turn brittle as well as fade.
Framed prints. A cover gives a little protection. Glass or acrylic sold as UV-filtering gives much more, and you can have a print reframed with it.
Tapestries and other fabric. Printed fabric fades in strong sun like any textile. Think of curtains.
Desk mats. A desk by a sunny window gets hours of direct light. A mat there will fade unevenly, with a darker patch where the keyboard sits.

What you can do

Choose the wall. This is by far the most effective step, and it is free.
Use the blinds. Draw curtains or tilt blinds during the hours when the sun reaches the picture. Sheer curtains cut a good deal of light and still brighten the room.
Fit UV window film. A clear film on the glass blocks most ultraviolet. It protects floors and furniture too.
Frame with UV-filtering glazing for anything you value.
Rotate. Move pictures between a bright wall and a dim one each year, so no single piece takes all the light. See rotating art through the seasons.
Put the hardy things in the sun. If a sunny wall needs something, hang a piece you are happy to replace in time: an inexpensive poster, say. Keep the pieces you care about in the shade.

What about lamps?

Indoor lighting is far weaker than sunlight, and it still adds up over years.

LED bulbs are the best for art. They give off almost no ultraviolet and little heat.
Halogen and old incandescent bulbs run hot. Keep them away from art.
Fluorescent tubes give off some ultraviolet.
Picture lights and spotlights: use LED, keep them at a distance, and turn them off when the room is empty.

Signs that a piece is fading

The colours look washed out or cooler than you remember.
One side is paler than the other, on the side nearer the window.
Lift the frame: the strip of print hidden under the edge is richer than the rest.
Paper has yellowed.

If you see these, move the piece now. Fading can't be undone, and it can be stopped from going further.

Fading and returns

Fading from sunlight is wear over time. It isn't a manufacturing fault, so it isn't covered by our policy on damaged or defective items. Where you hang a piece is the one thing we can't control, and it makes more difference than anything else.

Don't overdo it

Museums keep precious works in dim rooms because they must last for centuries. You are decorating a home. Ordinary daylight in a room, without direct sun on the picture, is fine. A print that hangs for ten years in normal indoor light and is enjoyed every day has done its job. The aim is simply to keep it out of the sunbeam.
