Hi Ricky
There are indeed two shades of Orleans blue mica, but both have the same paint code. I found this out when respraying the bonnet and bumper on my MA8. My paint supplier had two paint match cards, one slightly lighter than other (for the MA8 it was the lighter one). Both were B77P. There is another metallic blue these civics came in which looks similar to orleans blue but is a darker more blue (if that makes sense?) colour. I think Chandlers deck might be that shade. Its on a lot of later civic M's around the 2000 MY
