I suppose you’re new to all this, so I’ll try keep this simple.

First, I opened these psds: one, two. As you can see, the second psd is already enough for this cap, but I want to achieve slightly different colouring, so I added the other two after it as well. Now that you opened them all, your result should look like this. It’s ridiculous, I know, but you’ll delete some of the layers later. In “ezria” folder, I left only last three layers, since I want a greenish coloring, (not yellow or orange) set the Curves to 31% opacity. I added Gradient map and Vibrance and set it to 25%. Then I added Color fill (#9ea888) > Soft Light (opacity 30%)
I normally use my own psds, but since it takes me few hours to get a coloring I like, and they have like, 68467687 layers, I thought it would be easier for you to start like this, only adjusting the coloring first and then adding and creating your own layers. Here’s psd, if you want it.
I duplicated the base and then I used motion blur (Angle: 42, Distance: 2) as well as film grain (Grain: 3, Highlight area: 2, Intensity: 1) and in the end changed the opacity of the layer to 75% or so.
I was just about to close PS, but here you go. I’m not sure if it is okay to post it, since I used psd by Diana as well, tho I did not use the Gradient Map for the second image. What you can’t see in psd is that for the duplicated layer I had applied Film Grain (settings Grain: 2, Highlight area: 1, Intensity: 1 ) Filter to it, sharpened it and set it to 30%
There are more slightly different colorings you can get if you duplicate some of the folders and layers and play with opacity. There are also some layers I haven’t applied in second folder.
*Note: This PSD contains vibrance layer(s)

I don’t use many psds, but I definitely recommend caps-coloring, drunkandcoloring and Ley, they are my favourite, as well as coloring-mania.
