a stain for living cells?

[Rosie Redfield]

Hi,

I'm trying to grow Chilomonas (a cryptomonad) on agar plates.
Unfortunately the cells are
colourless, making any colonies that might arise very difficult to
see.

Does anyone know of a dye that would bind to the cells without 
harming
them?  I'd like to add such a dye to the agar to make small
accumulations of cells more visible.

Thanks,

Rosie
