The quick answer
When different light sources color different parts of a face, one white-balance adjustment usually cannot neutralize every area. If you can retake the photo, remove or avoid one source first. For an existing image, choose a believable overall balance, then correct the remaining area locally if your editor supports masks.
Check whether the problem changes across the face
Compare the forehead, both cheeks, neck, and a nearby neutral object. An orange cast everywhere suggests a different problem from an orange cheek beside a blue cheek. The latter can happen beside a daylight window with a warm room lamp still on.
Research on mixed-illuminant white balance explains why treating the whole scene as if it had one light source can fail. This diagnosis is about where the color changes, not deciding that every warm or cool patch must disappear.
Simplify the light before retaking
Find the boundary. Turn your face slowly while watching the preview. Notice whether the colored patch follows the lamp-facing side. Keep the camera position steady so the comparison is useful.
Remove one influence. Switch off a nearby lamp, move away from a colored sign, or choose a spot lit mainly by the window. Take another frame before changing any editing settings.
Check the neck too. A corrected face above an orange neck can still look disconnected. Judge all visible skin together while preserving the natural differences between areas.
Choose an editing response
Adobe's masking documentation describes adjusting selected regions. That capability belongs to the editor being used; this is not a claim about controls in Meluvya.
What remains
Useful response
Stopping point
A cast across the whole image
Try global temperature and tint.
Neutral objects improve together.
One differently colored cheek
Use a softly blended local correction if available.
The boundary stops drawing attention.
Strong colored light with missing detail
Keep the intentional color or choose another photo.
Further correction creates gray, patchy skin.
Keep a little of the room
A restaurant portrait does not have to resemble daylight. Try a version that keeps the warm background while making the face easier to read. Compare it with the untouched image at normal viewing size, then look closely for a visible mask edge.
Do not paint every cheek the same color. Shadows, makeup, and reflected surroundings can create legitimate variation. If correction becomes a collection of disconnected patches, the simpler choice may be the original mood or a retake.
Common questions
Can lowering saturation fix mixed light?
It can make the cast less obvious, but it also removes unrelated colors. It does not independently balance two light sources.
Is a blue shadow always wrong?
No. A cool shadow can describe the environment. Correct it only when it conflicts with your intended portrait.
What if my editor has no masks?
Try a modest global compromise, keep the color as part of the scene, or retake with simpler lighting. Avoid a promise of perfect recovery.
