# Light Modify

- Geometry
- Color
- Attenuation

Change here the color components of the new light (or list of lights, previously selected with Light->Select, when Global is pressed). Parameters for empty entries or Local choices remain unchanged.

### Ambient

These R, G, B entries change the ambient color of the new light. This can vary between black (0.0, 0.0, 0.0) and white (1.0, 1.0, 1.0).

This component emulates light scattered so many times, that it does not depend of the radiation direction, or the materials surface. Wired objects cannot reflect diffuse or specular light, so they need some ambient light to be visible.

### Diffuse

These R, G, B entries change the diffuse color of the new light. This can vary between black (0.0, 0.0, 0.0) and white (1.0, 1.0, 1.0).

This component emulates light equally reflected in all directions (as the light reflected by a hammered glass). Solid objects need some diffuse light to show its tridimensional shape.

### Specular

These R, G, B entries change the specular color of the new light. This can vary between black (0.0, 0.0, 0.0) and white (1.0, 1.0, 1.0).

This component emulates light reflected mainly along specific directions (as the light reflected by a metal). Solid objects need some specular light to show brightness effects.
