Here is an easy way to explain what you are talking about.
For home use LED lights that are bright daylight they use three different LED lights.
Red Blue and Green all packed into the little light source.
With these three they emit white light.
If you take out the green LED you get that crazy purple color because blue and red make purple but they dont seem bright but they are.
You do NOT want to look directly at these lights because they can damage your eyes even though you dont see them as being bright.
