is green poop always bad?

DD's poop has been more green than yellow in the past few weeks.  She's slowed down to going only every 4-5 days, whcih I know can be normal.  Instead of looking yellow and seedy, it's now runny and kind of olive green.  It's not mucousy, frothy, or bloody.  She doesn't seem to be in pain.  I struggled with supply problems early on, but was able to build up my supply.  I don't think I'm in oversupply territory.  Do you think it's a food sensitvity?  Or do some babies just have greenish poop?

ETA: If it matters, I'm still taking fenugreek, blessed thistle, and goat's rue.
