First, open your base, I used a pic of Cobra Starship.
Make a new layer, fill it with #94d469 and set it to soft light.
Make a hue/saturation layer:
Master saturation: +20
Reds saturation: +10
Yellows saturation: +9
Cyans saturation: +20
Now, make a selective color layer:
R: -100 +100 -40 0
Y: -100 -30 -10 0
C: +100 0 0 0
B: +100 0 0 0
N: +4 +5 -15 +5
B: 0 0 0 +100
Make anew layer, fill it with #68acaf and set it to luminosity at 25% opacity.
Now make a channel mixer layer:
R: +90 -6 +20
G: 0 +105 0
B: 0 0 +120
Lower the opacity to about 20%.
(This layer may not make a great different, so you can skip it, but I like the small difference it makes)
Now make a new layer, fill it with black (#000000) and set it to soft light at 10% opacity
(Again, this layer is not so important, but I like it's result, if the result you get is too dark, you can skip it)
Now you're done! I would like to see your results :)
