According to Wikipedia, a cyanometer is “an instrument for measuring “blueness”, specifically the colour intensity of blue sky. It is attributed to Horace-Bénédict de Saussure and Alexander von Humboldt. It consists of squares of paper dyed in graduated shades of blue and arranged in a color circle or square that can be held up and compared to the color of the sky”.
It’s probably too big of a task to make one from scratch for today’s Daily Create – although we’d love it if you did. Instead, why not visit Hello Cyanometer and browse though the images there, then remix one into something to share with us.
Alternatively, you could download one from Gavin Gough, print it and hold it up to measure the sky where you are.

@creating #tdc4881 #ds106 The blue of the sky is not on this cyanometer. (also here https://flic.kr/p/2r6Sn1t)

@creating #tdc4881 #ds106 I picked an image from the site where the sky was a soft, powdery blue, somewhere around shade 24 on the cyanometer.
