Title: working with colors
Post by: wmchauncey on February 20, 2015, 03:52:03 pm

I've got these smoke images, example below, that I want to introduce strands of different colors haphazardly,
kinda like an aurora borealis.  The smoke is on a separate selection if it matters. How might I do that in PS CC?

Selective color adjustment layer, or with a selection a hue/saturation layer with the "colorize" box checked. But there may be better ways to do it.

Using HSl with either colorized or hue changed, then use blend if and set it to only affect the lighter tones. Create another with a different hue, blend If only affecting the darker tones. Then play with gradients on the mask on each layer.

I did something similar, some time ago:

* Leave the smoke layer on top, and set it to "Luminosity" mode; no need to perform any selecting or masking.
* Create a new layer, below the smoke layer, and render some cloud-like random colors there.
* Adjust and tweak.

(PS: I did this using GIMP, not Photoshop; hope my translation from GIMP to Photoshop is accurate)

Using three different HSL layers that affects different brightness I blend if.
