When processing my IR images I find it gravitate to and usually enhance the blue tones, althought ocassionally I will dip a toe into the browns and will go a whole foot & ankle into the B/W.

Which doesn't really answer your question..., but if I had to choose only one I think I'd have to say the blues as I find the colour soothing.

 

They say a picture is worth a thousand words...

So where do they go when a photograph leaves you speechless?
