Reddit is not a bad place to search for new Liverpool Nike concept kits, as there are some designs on that particular publication that I have not seen on Twitter before.
The concept design pictured below was created by Reddit user @kubrickscope. The kit possesses a dark yellow and green colour scheme.
For the most part, the kit is dark yellow, but the logos are green. There is also a purple pattern which has been incorporated into the design.
I believe this kit would look decent if the pattern was not included. A lot of the Liverpool concept kits that I have seen recently have been ruined by the pattern that has been added to the design.
Dark yellow and green are two colours that combine well, but the pattern distracted me from initially noticing that.
