Yeah, scabbing isn't normally related to any specific color . . . it's usually results from the tattooist "digging in". It won't necessarily hurt the final outcome - but it does take longer to heal.
I'm not expert, although you can see from my Avatar I'm no stranger to red, but to me that looks more like an over-work issue than a color issue. If the first flower healed OK, why would they overwork the skin to pack in the color the second time?
