What it does
Thin highlights wrap rims and background objects; saturation is strong because the source is colorful and specular. They are poor frontal keys unless heavily diffused — their strength is separation and mood.
Light sources
Tube light
LED tubes (often RGB) paint edges and environments with line-shaped color — staple of neon-room portraits and music/editorial sets.

How to use this tool
When to use it
Neon rooms, cyberpunk fashion, music promos, and opposing-color rim lessons with a neutral key.
What to look for in the photo
Colored edge lines on hair/jacket; reflections in glossy props; background gradients; face should often stay more neutral than the environment.
Placement basics
Hide tubes behind subject or furniture; flag direct view into tube from camera. Gel or power-down until rims kiss the edge, not flood the cheek.
Distance & power
Low power on tubes relative to key; color reads faster than brightness. Use grids or flags to stop tube flare in lens.
Common mistake
Letting tube become accidental key on nose. Fix: flag tube toward background, add neutral soft key on face.
Pro tip
Complementary rims (teal/orange) read instantly — keep skin exposure neutral so color story stays on edges.
Practice on set
- Set neutral key on face first.
- Add one tube rim; meter until edge color appears.
- Add second opposing rim; flag spill off skin.
- Darken room ambient so tubes feel luminous.
Pairs well with
Flag / cutter
Flags (cutters, barn doors, black flats) block light — they subtract instead of add.
Color gel
Gels shift the hue of a light source — rims, backgrounds, and mood without repainting the room.
Snoot
Snoots choke light into a small circle — surgical pools for drama, hair lights, and cross-light kickers.
