I personally think it's a better deal than going to the 8-bit palette and getting three shades of tan where I've originally rendered ten of orange.
For consistency, it might be worth converting all of the flags to 24-bit format, so none get dimmed. If nothing else, it'll be easier to tell at a glance who controls what province.
(For the record, I'd meant his shield template, not the flag - when imported into Gimp, the layer that makes the last shield on the right grayscale for refused trade gets lost.)
