They've always stated that HUD colour hacking isn't officially supported and that the reason they've never supported it is because the colours are interwoven throughout the entire game and UI and that making it configurable is extremely difficult. I think we're just paying the price. It's a shame but I don't think we have a leg to stand on really.They already know that a) players fiddle with the HUD and b) it makes the UI look bad. I'd have thought they'd be more sensible than that.
Unless... unless it's intentional? As in.. in-game real HUD manager stuff?! :O ... could also just be lazy (read: easier).
