Hi Keith, thanks for tracking this down. Can you try this change:

modified   src/nsimage.m
@@ -310,6 +310,6 @@ - (instancetype)setXBMColor: (NSColor *)color
     return self;
 
-  if ([color colorSpace] != [NSColorSpace deviceRGBColorSpace])
-    rgbColor = [color colorUsingColorSpace:[NSColorSpace deviceRGBColorSpace]];
+  if ([color colorSpace] != [NSColorSpace genericRGBColorSpace])
+    rgbColor = [color colorUsingColorSpace:[NSColorSpace genericRGBColorSpace]];
   else
     rgbColor = color;

If that doesn’t work I’ll make your suggested change.
