the term,"Coerulea" seems to be applied wherever a variant tends toward a shade of lilac, the true blue remains as elusive as ever until one sees some of the Australian terrestrials. There are now a number of phals described as being blue, & they do have a sort of blue tone to the lilac shade. Very pretty, but blue? not to my eye. Those treated blue ones are sad fakes, like the dyed tropical fish coming out of the far east & selling so well in pet stores. Genetic engineering may do the trick, but nature's own phals ain't got no blues.
