Colors for a mountain ridge

Hey there, Sorry I didn't see your question sooner. I'm no expert on groundwork, let's get that out up front. But first question for you, are you painting a backdrop (2-D) or a built-up mountain (3-D)? This helps to determine perceived distance from the veiwer and technique. Next, what is your setting? Different mountain ranges have a different "base" color depending on there basic composition. I live in the Missouri Ozarks and the dirt around here is generally a tannish color with variations toward red. Best suggestion, look at pictures of the area you are modeling. As far as lighter or darker first, conventional wisdom says start with a base color, then give a dark wash for the crevices followed by dry-brushing on the highlights. Hope this helps. Happy Modeling!

Have a look at some scale railway forums. They deal with these issues for their layouts on a regular basis. The geology of the region os very important, so know your location and look at pics of the real thing.

 

Good suggestions so far, but the best reference for painting & finishing a mountain range is... a mountain range! Get outdoors and take a look at one with your own eyes. Note the colours, shades, hues, shadows, etc. Take plenty of photos & notes for your future reference.

Next best thing is a Google Image search. Failing that, look at some landscape picture books (the tourist souvenir type are good for this). 

Hey there, me again. Geomodeller had a good idea about the reference photos so here are a few...

Maybe this will get the creative juices going. Hope it helps
