particle additive soft light depends

hi all!
I'm searching a shader for my particles (smoke) like the particle additive soft but that is influenced by the light..
the shader above is good, but for example, a white smoke.. is white at midday like at midnight.. and I wish at midnight that is 'blacky'

have you got any ideas about this??

I'm on deferred / hdr / linear on windows desktop
thanks in advance!

 

Do you need the smoke to have thickness, in other words volumetric? Or is it okay if the color is adjusted strictly based on light color/light intensity?

 

thanks @DouglasPotesta 1 for me is ok have the color adjusted by the light and the particle be 'soft'

 

Here is a really simple one. I made it multiply because you don't want to additivley blend for smoke, it causes the smoke to get brighter, when it should be darker.

 

wow! thanks @DouglasPotesta ! I'll try!
