I called this Scrumble ‘Fifth Colour of the Rainbow’.
Did you know that there aren’t a lot of blue things in nature? Even the word ‘blue’ didn’t enter the human vocabulary until artists started using a stone called ‘Lapis’ to make a blue pigment for painting. Because lapis was expensive, it was reserved for special projects. Much later, the discovery of the element cobalt made the color blue more affordable.
Puns to keep you from being blue:
A small step for cyan, a giant leap for bluemanity.
Nerves of teal.
Azure headed into town…
Are there any cobalternatives?
What part of no don’t Blue understand?
