I'd have put *that* the other way around. ;-) In Glorantha, the sky is blue purely due to the 'blueness' of water -- at least according to that myth, which seems to be the dominant one in 'central Genertela'. But in the RW, the blueness of water is due to a number of factors -- reflection, yes, but also internal refraction, and also depends on the composition and clarity of the water, the appearance of the bottom in some cases, and what-not. (Which is why the colour is as variable as it is.)

Cheers,
Alex.
