Creating Gradients can someone help me edit/create?

Hi guys! Looking to see if anyone would be able help me switch the color of some gradients? I don't have the original PSD file, but I would really like to switch it from a brown to a nice orange and yellow gradient. Any tips? Couldn't make it work in photoshop...
photos are in the drive below!

Hi,
Did you manage to get this done?
It is not that difficult.

Hope this is what you wanted:

Put it in photoshop, create a gradient map and play with the color maybe.
