Yeah, it's the paintkit used to create repaints, I copied one of the Red Arrow .CFG entries and changed the "texture=" entry. I'm totally stumped!
I see your possible uncertainty Ben
Mike.. just to make sure we're all singing from the same sheet, I take it you've done a repaint using the PK then used one of the aircraft.cfg entries as a base for the new paint and changed the texture= line to the new paint. Make sure you not only change the [fltsim.XX] line but other entries too. Here's the entry for paint 1 (front seat).
[fltsim.0]
title=BAe Hawk T.Mk.1 FrontSeat Red1
sim=HawkT1
model=frontseat
panel=
sound=
texture=XX308
kb_checklists=HawkT1_check
kb_reference=HawkT1_ref
ui_manufacturer="BAe"
ui_type="Hawk T.Mk1"
ui_variation="Red 1 W Cdr Jas Hawker"
ui_typerole="Single Engine Jet Trainer"
ui_createdby="Skysim"
atc_id=RED1
atc_airline=AIRFORCE
atc_flight_number=308
description=Red Arrows 2008 "Red 1" W Cdr Jas Hawker

You have to change the fltsim.XX number to the next corresponding number AND change the title line (eg.. title=BAe Hawk T.Mk.1 FrontSeat Red
2 . Also change any other info that isn't relevant to your new paint (eg. ui_variation/atc_id/atc_flight_number/description. FSX doesn't like seeing 2 (two) of anything the same and will spit one out if it doesn't like it
