[Radiance-general] color of the light source

[Bei Xiao]

HI,
 Thank you all very much for the previous replies.
 I have another very rudimentary questions about the rendering. I use
a point light source in my rendering of the following parameters:
void light bulb_light
0
0
3 5000 5000 5000
Am i suppose to render the scene with white color?
But this light source illuminate the room with yellowish color. How can I
get the white illumination? Is there any parameter that I need to set to
get the correct color of thelight?

Thanks a lot.

Bei
