check, there is a recent review by R. Tsien in Nature Methods. I would guess Sapphire is like Vex, which we have used. Vex is excited using a 407 nm laser. We use compensation to correct for spillover caused by the small amount of excitation by the 488 nm laser.

Subject: GFP and Sapphire
I am wondering where I can find the excitation/emission spectra of the
fluorescent protein T-Sapphire - does it exist? We are finding that the
488 laser is exciting T-sapphire as much as or more so than the UV line
and thus hinders our ability to use GFP at the same time. Would using a
lower laser power on 488 help with this?
