Hi guys,
I'm trying to work out what strings came with my bass when I bought it used. They're roundwounds and don't have any silk wrap. The ball-ends are coloured as follows:
G=green
D=black
A=red
E=gold brass
I seem to remember that D'Addarios had similar colouring when I had a set about 14 years ago, but I'm not sure. Anyone know what they could be?
Do the colours give any indication of the gauge? I just strung my bass with a set of Ernie Ball 45-100 flats but these seem lighter than the rounds I just took off (and brighter

but perhaps that has more to do with the fact that they are new).
