And some exterior Craftsman colors here: http://www.thisoldhouse.com/toh/photos/0,,20723440,00.html

There is no one color palette that is correct for your home. Generally speaking, Craftsman homes utilized rich, earthy tones when they were first introduced. This was a departure from white clapboard colonials and brightly hued Victorians. Rusty reds, deep pine and sage greens, tans and golds are all "period appropriate" choices. However, this is a new century! Be bold! You can pay homage to your home's history, but put your own unique spin on your color scheme. I would suggest finding an object with colors that speak to you. This might be a rug, a painting, a piece of pottery, etc. This is your "inspiration piece". Pull colors from this object and choose others that work well with it. Don't be afraid of color, but be aware that when using a strong shade, a little goes a long way. Choose the tamest colors for the larger spaces and reserve the accent colors for a front door, a powder room, a dining room ceiling, etc. Above all, do what pleases you!

I think it is nice to tie the exterior and the interior design with the home's history when it's consistent with your preferences.

Just painted my 1923 Craftsman a sage green with ivory trim and I'm painting my storms a dark brown to resemble period storms.

So happy to see someone wishing to stay within the original style of their period home. Kudos to you!

There are still color palettes from that era to look at on line. Google "arts and crafts color palette" and a few Pinterest pages of colors from Aladdin Homes will show up. Aladdin was a kit house manufacturer and prepped packages for Sears as well in that time period.

Behr paints (from Home Depot) has a collection of Arts & Crafts colors as part of their Home Decorators Collection color set.

Not all commercial paint company "Historic" colors are accurate, so do some checking first. There are some scanned original period paint charts available on line (try a google search for original 1910 paint color charts) or check independent resources. You might find the chart here helpful, although you should always remember that the colors will look a bit different on different types of computers/devices/monitors. In general, stick as close as you can to natural and earthtone colors for this period.
