Getting colour accurate from easel to screen

Colour complaints on artwork are unusually damaging, because unlike a size error there is no objective standard to appeal to. The buyer says the blue is more purple than the photograph; you look at the piece and you are not sure they are wrong.

Almost always the cause is one of four things, and all four are controllable.

One: your light has a colour

Every light source has a colour temperature, and your camera guesses how to compensate. A warm household bulb pushes everything orange; an overcast sky pushes everything blue; an LED with poor colour rendering does something unpredictable to specific hues, most often desaturating reds.

The fix is to pick one light and stay with it. Daylight from a north-facing window is the traditional choice because it is consistent and relatively neutral. Whatever you choose, do not mix it with another source — the two casts cannot both be corrected.

Two: your walls are painting the light

This one catches almost everybody. Light bounces off surfaces and picks up their colour before it reaches your artwork.

Photograph a piece in a room with a red feature wall and everything acquires a warm tint. Photograph it on a lawn in summer and the whole piece goes slightly green from light bouncing off grass. The effect is strong enough to shift a colour by a visible amount and subtle enough that you will not notice while shooting.

Photograph against and surrounded by neutral surfaces. If your studio has coloured walls, hang white sheets for the duration.

Three: your phone is improving things

Modern phone cameras apply significant processing: saturation boosts, contrast curves, sky enhancement, skin-tone adjustment. These are tuned to make holiday photographs look pleasing and they are actively harmful for reproduction.

If your camera app has a professional mode, use it and turn processing down. If it can shoot RAW, do — RAW files bypass most of the interpretation and give you what the sensor recorded.

Failing that, shoot as normal and then reduce saturation slightly in editing. Phone processing almost universally over-saturates, so a small reduction usually moves you toward accuracy rather than away from it.

Four: nobody's screen agrees

Even with a perfect photograph, the buyer's screen is not calibrated and neither is yours. This part you cannot control, and it is worth accepting rather than fighting.

What you can do is give the buyer a reference. Photograph the work next to something whose colour they know — a white sheet of paper is the cheapest option — and their brain calibrates automatically. If the paper looks white on their screen, the colours near it are approximately right.

Use a reference card if colour is critical

For anyone selling originals at serious prices, a colour reference card is worth the small cost. Photograph one alongside the work in the first frame of every session, then correct the image until the card's known values are correct. Every subsequent photograph from that session gets the same correction.

This is what reproduction photographers do and it is not complicated. It takes one extra frame per session.

Say it in the listing

However careful you are, some variance is unavoidable. A short line in the description — "colours may vary slightly between screens; photographed in daylight without filters" — sets expectations honestly and heads off most complaints before they arrive.

Sellers sometimes worry this sounds defensive. It reads as professional, because it is what a professional would say.

What survives restaging

Colour is preserved from your reference photograph rather than reinvented, which means an accurate photograph stays accurate through a room mockup and an inaccurate one stays inaccurate. Staging changes the surroundings, not the piece.

That cuts both ways and is worth stating plainly: get the colour right at capture. Nothing downstream will fix a photograph taken under a warm bulb next to a red wall, and everything downstream will faithfully preserve the error.
