I've set up a scene where the only lights that are on are a couple of red spots and one blue spot.  But everything looks like its lit with white light.

I double checked to make sure there weren't any other lights (with these lights off, the scene is totally dark.). Any suggestions?  Its a superfly render, BTW.

Here's one of my light settings.

My guess is that it's just light bouncing off objects, for example a white wall behind the camera. Superfly simulates that kind of thing.

Hi. Try lowering the intensity setting of your lights, to say 50 and do a quick test render. This mayby too dark, but you shoud see the effect your after.

Thanks for the suggestions, but there's no wall behind my camera to reflect light (and all the other walls in this scene are dark brick colored).  I already  tried turning down the light intensity.  Definitely less bright, but still white light.

I'm baffled.

I had an issue where I needed a colored light. I had copied one of the lights in the scene and changed the color and it stayed rendering white. I ended up needing to create a new light and making it green. Then I decided I needed 2 green lights so I copied the green one and it rendered white. Again, I had to create a new light. Did you copy lights or make new ones?

I agree that the intensity of that one light is very overwhelming but you should still see its effect on the scene.  We really need more information about the scene setup.  Is there an environmental background surrounding the set?  Are you certain about the light count you are using?  Double-check the Light Controls.  I seriously doubt that ambient reflection in Superfly will have any effect on the lighting as odf is suggesting especially if you claim that only 3 lights are present.  Test render with each individual light on and see if you have the intended effect.  I don't know where your lights are positioned but in testing the Dist End setting on the parameter, my spotlight barely reaches the scene from its present default position.  We really need more information.  And as an aside, you have some very bad shaders on your models in the scene, self glowing is one of them.  But that is a different issue.

RedPhantom -- I didn't copy them, but they were a light set that I applied that was supposed to work with that particular scene.  Maybe I just need to delete them and create my own from scratch.  I'll try that next.

Hborre -- The spotlights are only about 15 units above the ground, so I would think at that distance that Dist End should work.  As for the self lighting on some of the models, I turned all ambient settings off on them so that when I tried to render with no lights it was completely dark.  I kept them that way for this render, if that's what you're takling about.

My thoughts are that somewhere/somehow there's a green component in the mix... R1+G1+B1= white... or perhaps there's so much combined intensity it over-rides individual components... I think I'd try giving the scene a pleasant low light ambience before adding (small) spots for effect..... Just a thought.

Y'all have a Great Day.

I would try changing the green and blue settings to 0.0001 instead of 0. Not because there is a good reason that should work, but just in case there is a bug about 0.....

Also, try turning off all the lights except one. Test them individually. That might tell you more about whether the issue is affecting each light or there is something about the interaction between them.

Turns out that just replacing the spots and starting over did the trick.  I don't know why the original ones made it white, because I deleted them and created new ones with exactly the same properties and now it works fine.

Weird!

Thanks for all the suggestions!

I've noticed that VENDOR lights have lost their color - to fix it, I added a "simple color" node with that color in it - works every time for me.

I believe that you need to plug a simple color node into the light color port in the mats room. Then you need to adjust your color from the simple color node.
