Emissive surfaces (neon, screens, lava, glow)
Emissive surfaces are objects that appear to produce light, such as neon, screens, lava, and magic glows.
What it is
Paint the object and the sense that it emits light. Emissive surfaces include phone and monitor screens, neon tubes, magic spells, lava, LED strips, and UI holograms.
Place emissive areas among the brightest values while preserving structure. Simplify local form when needed, then use strong shapes, edges, and controlled bloom, the soft halo around a light source.
Show the colored light affecting nearby surfaces, such as pink spill from neon or light beneath rocks near lava. Emissive materials include the object and the light it casts on the scene.
Why it matters
Emissive surfaces support the light hierarchy, night scenes, and integrated effects. Weak control can make them look pasted on, flatten their form, or leave nearby surfaces unaffected. Excessive saturation and value can turn screens into white rectangles, neon into disconnected outlines, or lava into orange shapes.
You can check it when
- ✓Keep emissive areas among the brightest values while preserving structure and avoiding featureless white areas.
- ✓Place a glowing object in a dim scene and show its light affecting nearby planes through color spill, rim light, or under-lighting.
- ✓Compare the object with its emissive feature off and on. The on version changes the lighting of the environment, not only the object's color.
- ✓Shape glows and blooms to follow perspective, form, overlaps, edges, and light direction.
