That's going to be a trial and error chore; looks like there is some light tan and a light gray, you may be better using a wash rather that actually using straight paint.

Okay, AMERICANA by DecoArt. DA03 Buttermilk
DA257 Bleached Sand
Use Burnt Sienna in tiny amounts to darken. Make a light wash and build up
I took a picture of a nearby river to the local Home Hardware and they matched the color perfectly, could try something like that?
From building military models, I learned the combined techniques of washes / drybrush. After painting your model, you apply a wash to simulate shadows. That is followed with a drybrushing of a slightly lighter tone of your base paint to simulate highlights.
Sometimes I struggle with both... and sometimes, I feel like I've gotten it exactly right. The latter times are the ones I really enjoy!
I'm assuming you are familiar with both washes and drybrushing. If not, it's easy to find plenty of references all over the Internet. And don't limit your searches to model railroading -- sometimes seeing how another segment does their models will teach you just what you need!

Zoegraf,
Very nicely done -- and thanks for posting the pictures!
I love working with scenery; in most cases, the precision needed to finish an engine, a piece of rolling stock, a building, etc. is not needed for scenery. Most of Mother Nature's works do not have straight lines or a specific, distinct color -- which makes it easier for me to get it "right".
Regards,
Tom
One thing to remember is that whichever paint you elect to use, or washes, they won't look the same in sunlight as they will indoors under various types of lighting. That means your photos won't look the same, either. If the diorama is strictly for outdoors photography, then make sure your paint choice looks the same as the photo does outdoors.
Your rocks look very good!
Depending on whether you have actual access to the rocks you are trying to replicate .... the best match you will ever get is to just use the real thing ! Most times, you can find smaller rocks in the same area.
Sounds crude, but most rocks will break down with a heavy handed hammer under a towel to keep them confined. A lot of rocks have almost a three-dimensional coloring that is almost impossible to replicate with any kind of paint.
