I decided that the Ibanez should be an ivy green, and that the olp should be a sky blue. My girlfriend helped my pick out the colours because the majority of my guitars are white black or sunburst.
The "After" photos aren't so great. Artificial lighting and a not so good camera phone. I'll try to take some better photos in the sunlight. I'm really enjoying these colours, they're totally different than what I've got. The ibanez will have a black pickguard and the olp will have a white pearloid pickguard. I think the finished basses will look pretty good.
