POV-Ray's lighting rule is: color of light_source * color of diffuse texture =
output color, when lighting is perpendicular to the surface.

So if you want a light gray output like rgb<0.8,0.8,0.8>, then you can put a
light_source{ color rgb <1,1,1>}
 with texture{pigment{rgb <0.8,0.8,0.8>} finish{ambient 0 diffuse 1}}
