How to change color (glow) in png image

Hello,

I have a black spider with red logo on its back.
I would like to make the red logo glows.
There is a way to target that red logo ?

Thanks
Marco

Soft glow has a threshold. Since the red is brighter than the black you should be able to use the threshold to only make that glow.

Or you could use a keyer to remove the black, blur the red parts and merge them back onto the original image.
