I was able to fix this problem on my OS X 10.6 machine by modifying nsterm.m:

diff --git a/src/nsterm.m b/src/nsterm.m
index af1f21a..696dbdc 100644
--- a/src/nsterm.m
+++ b/src/nsterm.m
@@ -1389,7 +1389,7 @@ ns_get_color (const char *name, NSColor **col)
 
   if (r >= 0.0)
     {
-      *col = [NSColor colorWithCalibratedRed: r green: g blue: b alpha: 1.0];
+      *col = [NSColor colorWithDeviceRed: r green: g blue: b alpha: 1.0];
       UNBLOCK_INPUT;
       return 0;
     }


After the change, the RGB values of the colors displayed matched the expected RGB values according to the DigitalColor Meter utility.
