Global superstar Beyoncé has hinted at the origins of her daughter's name with a new Tumblr post.

The 'Halo' sensation gave birth to her first child, baby Blue Ivy, at the beginning of the year and shared an excerpt from Rebecca Solnit's 'A Field Guide To Getting Lost' on the blogging site earlier this week that features heavy repetiton of the word 'blue'.

A particularly poignant passage from the few paragraphs Beyoncé chose to send out to her followers explains that "the beauty of the world" can be found in the colour blue:

"The world is blue at its edges and in its depths. This blue is the light that got lost. Light at the blue end of the spectrum does not travel the whole distance from the sun to us. It disperses among the molecules of the air, it scatters in the water. Water is colourless, shallow water appears to be the colour of whatever lies underneath it, but deep water is full of this scattered light, the purer the water the deeper the blue.”

"The sky is blue for the same reason, but the blue at the horizon, the blue of the land that seems to be dissolving into the sky, is a deeper, dreamier, melancholy blue, the blue at the farthest reaches of the places where you see for miles, the blue of distance. This light does not touch us, does not travel the whole distance, the light that gets lost, gives us the beauty of the world, so much of which is in the color blue."
