Kill the cyan tube so only the warm desk lamp keys his face — the room goes amber and you see what the practical alone buys.

Final look

Base setup

Separating color roles makes mixed light readable: the tube sells modern accent and separation while the desk lamp keeps skin trustworthy and warm. Learners see how rim color can be bold without poisoning the key.

Key notes

1Power the tube low — it is separation, not a second key; if the face goes magenta, the tube is too bright.
2Keep the desk lamp motivated in the frame or its base visible so the warm key feels real.
3Hide the tube from the lens with subject body or flag the tube toward the hair, not the cheek.
4White-balance for skin on the lamp; let the tube stay intentionally off-neutral.
