The crystal colors are: Dorado, Lt. Co. Topaz, Golden shadow, Smoky quartz and sand opal.
The metal plating color is: Antique Brass 
Designing jewelry that is combining the same color of metal and crystals, would make a beautiful total look that is all about that one main color.
When using SW crystals such as sand opal, light Colorado Topaz and Golden shadow, you get a bright, golden sparkly look.
When using Dorado, Greige, Smoky quartz and Bronze shade you get a darker and a deeper tone of brown.
As in this inspiring, when you focus on one main color, you can really play with the different tones until you get the look you were looking for.
These warm brown tones are a perfect look for the upcoming autumn and winter season, that soon will be here.
You can see all of these jewelry bases and crystals in the "Components" section.
Have fun creating!
