In the Western world the peacock has been used as a motif in art and design at least since early Christian times. In its earliest and medieval incarnations the peacock symbolized Christ’s resurrection, renewal, rebirth.
Apparently the peacock also symbolizes pride but let’s not go there. Pride is a vice and really overplayed these days (in my humble opinion haha), when it comes to the song and dance some of us call “civilization”.
The peacock is also India’s national bird and has come to represent royalty, grace, joy, beauty and love.
Peacock blue of course is a distinctive hue, one of my favourites when it comes to shades of blue.
