Hi - my idea behind the concept was to keep the same design for all 5 divisions, and only change the position and the color around the circle shape. This was we can easily add the name of the division below each logo.
I also have the idea of how to make it work in black and white - the shapes that are now indicated by colors, can be outlined and not filled as the rest, or the opposite. Please let me know if you'd ne interested to see what I mean, and also, would you like me to play with the colors or anything else?
