A simple approach would be to collect more data so
that the precision would be adequate for color compensation.
Judging from the subject (triple label) I would guess that
you are using GFP to identify cells in which to look for
CD34 and CD38 which have longer wavelength dyes attached.
If this guess is correct you could use an inducible promoter
for the GFP to reduce the signal size and therefore the
