when i pulled my speaker grill to remove my speaker i noticed the original blue was darker than the bright blue. i bought bright blue interior paint a few years ago and repainted the radio side covers and it was a match to what was there. i had noticed this darker blue on some edges of the dash pads but just assumed they were re dyed dark blue pads. i see no evidence my dash was ever changed and there is no doubt it is a 450 interior car. any ideas?
