_DSC4243-Rose-composite

Not a color swap or channel swap. Composite image. Brightness from the normal picture. Color from the UV/IR difference.

 

I'm not sure if the colors can be said to have come from one kind of light but I'm sure most of this is caused by invisible light. Infrared and a little bit of UV. At least UV-A

 

Lens was a Tokina 100mm Macro stopped down to ƒ/16
