OK I will try to explain this as good as I can.
I used EffectsLab pro for a small video I was doing, and I used the partical engine to make colorful smoke and put another video in to add to the smoke(WITHOUT A GREEN SCREEN). But when I add the video all the dark colors are taken out and the bright colors (like white) are still there.
What do I do to keep all the colors in the video there?

A quick question: Are you talking about the video of the smoke that you added in during editing being transparent or the actual footage?

Alright, let's fix this, shall we? On the layer that is transparent, the problem is that the composite mode is on screen or add, either way you loose the black in your image. I don't know how to get it back, sorry.

Officially, you can't. Video compositing of that sort is beyond the scope of EffectsLab's abilities. However, not-so-officially, there are a few workarounds.
Firstly, you could transcode the footage to a codec that supports alpha channels, so that there was an alpha channel present assigning all of the frame to be opaque.
Secondly, you can combine all of the footage clips that you wish to use into a single clip in your video editor, then import that big clip into EffectsLab, then slice it back up into the separate clips on the timeline.
Thirdly, there is a trick involving an Object mask, and using the alpha channel from the first clip to control the transparency of the second. I don't recall the exact process offhand, but there is a tutorial on it in the Tutorials forum.
But still, if you want to be able to combine different clips in this way, and have any degree of control, then you should look into getting an app that actually handles compositing, like CompositeLab.
