How to change leaves to brown shades

How do I change the leaves colours as in 2nd pic with a mask/layer. New to PS

Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible? 

If the leaves aren’t on Layers of their own the image would be pretty bad (edit: for this task, that is) because the masking would probably need considerable manual editing.

That was the second image, so I assumed that was the color you wanted to achieve. 

So it’s the other way round and those should become brown?

Solid Color Layers set to the Blend Mode Color might help, the Luminance might need amending – a Curves Layer for example.

Yes, sorry. The desired result is your image. Last question: if you look at my desired image(first one) , the orange hue is darker/more intense around the darker leaves. How is that achieved?

[c.pfaffenbichler]

When you have created a Mask for the green part you can not just edit the hue, but you can add a Curves Layer to change the brightness/luminance. 

Or do you mean the background?

See attached. Darker hues

You can use Adjustment Layers (or multiplying Solid Color Layers) with a manual Mask or a Smart Object-duplicate of the leaves set to multiply etc.

Tx. And then the overall fill with those varied hue intensity?

Another possibility.

Add a Selective Color adjustment layer.

Set something like this for Greens.

Something like this for Cyans.

Looks nice. And then the overall fill with those varied hue intensity?

You could use Color matching. I did not mask but that should be easy task with object selector

From 2 to 1

From 1 to 2

Also Hue saturation could be a way to achieve this purpose

You can also use the HSB/HSL Optional plugin to shift the shades to the desired range.
