What you will get

Your photo with the colour cast removed, whites that look white, natural skin tones, the original mood and every detail and person unchanged.

Common mistake

The fix swings too far and looks cold or pink.

Fix: Say “correct only part of the cast and keep the warmth of the evening light”. A mood in the photo can be wanted.

Also watch for

Skin looks grey. Name the problem, “skin tones should stay warm and healthy”. Point to a real white object such as a shirt, wall or paper.
Only part of the photo is fixed, as in mixed lighting. Say where the cast is, such as “window light is blue and the lamp is yellow”. Mixed lights may need two passes.

Try a variation: check with a grey card

For future photos, include a white sheet or grey card in a test shot under the same light. Show it to the AI and say “use this as the reference for white”.

Keep every detail the same. Make the white wall truly neutral and keep a slightly warm feel on the faces.
