In quite a departure from this season's kit, the 2021-22 design features a zig-zig pattern on the front and check pattern on the sides, both in two different shades of blue.
The sides are also highlighted by a vibrant yellow, while the club badge has a yellow border alongside an all-yellow Nike tick.
The main blue colour is described as 'Lyon Blue' with the yellow named as 'Opti Yellow'.
The Three logo is the standard white.
The shorts have the same zig-zag pattern on the front with check-and-yellow look on the sides. Again, the Nike tick is yellow.
The new shirt could reportedly go on sale this month ahead of the end of the current season.
An off-pitch collection, including an all-blue polo shirt and jacket with the yellow highlights, has also been reported elsewhere.
