We need simple but smart logo, there are no restrict guidelines so feel free and be creative in your designs.
You can use orange and blues and may be some grays, but that is not limited and you can pick other colors also, but please keep it simple.
1- Please do not overuse shields, we want to see something else and new ideas.
2- The logo should be clear on small size (ex: 40x40 px), so it must not be very crowded and should be simple.
3- Till now very few logos focused on Republic side, we wish to see some ideas related to that.
4- you may also highlight on football fans in the design.
5- It will be great if you can combine 3+4
