Royal blue. Almost the exact same color as LaBellas. They purportedly are the same as Fender Flats lately, but Fenders have emerald green silk. At least from what i hear.
Chromes have a midrange metallic Gank and sustain a lot like rounds.
LaBellas have a warmer, thumpier, more fundamental tone. They are also more polished, smoother to the touch. Although most LaBellas are a heavier gauge, they feel more pliable to me, offsetting the perceived tension difference.
