Words meaning blue-gray/grey (the most common name), or gray/grey-blue, bluish-gray/grey, or grayish/greyish-blue:

In English:

clair de lune, "pale bluish-gray"
Copenhagen blue, "[mild] greyish blue"
slate, slate blue, and slate gray, "having the [dark] bluish-grey/gray colour of slate"
but "blue-gray" is more common than "slate blue" or "slate grey", and "slate" is too polysemous to compare
Wedgwood blue, defined (apparently correctly) as "a pale grey blue colour" but with a dark colour swatch

See also perse, "dark greyish blue (or purple)", and more distantly bloncket, gainsboro, gunmetal, and petrol blue. Compare also caesious and glaucous.
