Vantage 4.3, bearing color codes

[paralis]

Hello to all Aston enthusiasts

I´m overhauling a 4.3 engine and unfortunately I couldn´t find any of the color codes of the main and conrod bearings. Based on the information in the workshop manual it should be on the edge of the bearing shells. But there is nothing. Is there a way to decode the numbers from the block with the numbers on the crankshaft to get the right codes ?

For the main bearings we have:

Upper: Blue/Green, Blue, Green, Yellow
Lower: Blue/Green, Blue, Green, Yellow

conrod bearing we have:

red
black



Thank you
