The Old World robin, of the family Muscicapidae, lays eggs of various colours, but according to the BBC, all have "a whitish ground colour, [and] a speckling of reddish or reddish-brown spots". The New World robin, on the other hand, of the amusingly named Turdus genus, lays eggs with a very striking turquoise colour. So much so that the crayon company Crayola has, since around 1993, produced a crayon called Robin's Egg Blue. Crayola's robin's egg blue (#00CCCC, ●) is much darker than the robin's egg blue I've used for miscoranda's redesign (#E6F2F2, ●), but the darker colour is much too overpowering on the screen.
According to Wikipedia's article on the name Robin, "In England it is generally regarded as a male name, although it is sometimes given to females. In the U.S., it is more popular as a female name than a male one." This is somewhat suprising since the European Robin is much more small and sleek and cute; one would think it'd be a female name in England. Perhaps in some other parts of Europe it is.
John Cowan wonders whether the connection of Robin to Robert (etymology of robin: 1549, shortening of Robin Redbreast (c.1450), from O.Fr. Robin, personal name, dim. of Robert) is remembered in the U.K. to a greater extent than the U.S.
John also noted that he's "fond of the bit in The Once and Future King where the Wart (the eponymous hero) hears of 'Robin 'ood', asks who he is, and is told, 'Nay, since th'art a scollard, tha must speak his name scollardly', i.e. 'Robin Wood'", which got us wondering about the word scollard. The OED doesn't list the word, but does contain "scollardicall", which then references sense 3.c. of "scholar", which is "Freq. in vulgar or dial. form scholard, schollard, etc."
In the United Kingdom, it is more traditional to refer to robin's egg blue as duck egg blue. One such duck that lays blue eggs is the Dutch Hookbill, which was referred to "in Willughby's Ornithologie in 1678", but may have an eastern origin. I wonder what kinds of avian blues there are in Chinese?
