John,
There are darker blue forms (including some on my land), but most of the ones I saw on this walk were pale (one might think of Hyacinthella leucophaea, which does not occur on Cyprus - unless I have just discovered it here!). Meikle describes the colour as 'pale blue'.
I am familiar with the species only from the Akamas Peninsula and nearby areas, where pale to very pale blue seems commonest. I can't speak for other parts of southern Cyprus.
BTW, I have checked, and I am pretty sure my ID is correct; it is neither Bellevalia nivalis nor Muscari parviflorum.
Of note perhaps: the pale flowers in my photo still have violet anthers (just visible) and purplish stems.
Here's another pale one, however, with no blue/violet at all - not in the petals, anthers, stem or leaf bases. I found it in pine woods further south on the Akamas, on 26dec09. In the same, sparse, colony there were more normal pale blue forms, the pigment tinting the petals, anthers, stem and leaf bases (below).
