While you're waiting for an authoritative answer I'll give you what I know.
I'd use the bezier selection tool to select the trim, eavesdrops and spouts,
but not the roof, trees, etc. Then I'd Rightclick->select->bycolor, click the
"intersection radio button, use a threshold somewhere in the 10-25 area, and
click a portion of the drawing, inside the selections, that has one of the
lighter parts of dark brown. This will select all sorts of stuff. Then I'd
make the foreground color a lighter shade of montana tan, and
Rightclick->Edit->fillWithForegroundColor. I'd repeat the same thing for a
slightly darker part of dark brown, replacing with a slightly darker montana
tan, and so on til all the dark brown on eaves, spouts and trim are replaced
by montana tan.
My method will eliminate quite a bit of texture. I'm sure some of the other
people on the list will come up with ways to replace all the brown at once,
texture and all, and I'll anxiously await that information. But if worst
comes to worst, you can do what I just said -- I've done it often.
By the way -- I use select by color a lot when I scan yellow receipts. I use
select by color to turn the yellow to white, then save it as grayscale and
save mucho megabytes.
