'Coventry' blue is a pretty, near-primary blue, with undertones of purple. Not quite a periwinkle, but definitely on the cool side of blue. Maybe you could call it royal blue.
NOTE: In general, use the individual color image as your guide. I have devoted many, many hours to adjusting the images to match the actual wool color, but the usual disclaimers (about colors appearing different on different monitors) apply.
HOW TO ORDER
The standard minimum size available at Ram in the Thicket is a 3" X 18" increment, and each of those represents one "item". So from each listing, order the total number of increments of that color you would like. If you order more than one 'item' of any color, I will send it out as one large piece.
