Air Force blue colours are a variety of colours that are mostly various tones of the colour azure, the purest tones of which are identified as being the colour of the sky on a clear day.
Some air force blue colours, notably the air force blue colour used by the United States Air Force and the colour used by the US Air Force Academy, may look like they are tones of blue instead of azure (On the RGB colour wheel, which has 12 major colours, blue is the colour at a hue code of 240 degrees and azure is the colour halfway between blue and cyan at a hue code of 210 degrees.). However, they are actually dark tones of azure, not blue, because their hue (h) codes are between 195 and 225, the signature of a tone of azure.
These air force blue colours are used by these various air forces for colour identification.

“Make me a willow cabin at your gate,
And call upon my soul within the house;
Write loyal cantons of contemned love,
And sing them loud even in the dead of night;
Halloo your name to the reverberate hills,
And make the babbling gossip of the air
Cry out “Olivia!” O, you should not rest
Between the elements of air and earth
But you should pity me.”
—William Shakespeare (1564–1616)
“Throwing open the door, she brings forth the veritable queen of all the souffles, that spreads its archangelic wings over the entire kitchen as it leaps upwards from the dish in which the force of gravity alone confines it.”
—Angela Carter (1940–1992)
“They said, “You have a blue guitar,
You do not play things as they are.”
The man replied, “Things as they are
Are changed upon a blue guitar.””
