Talk:Distinguishing coloring

I don't get it
Can someone please dumb this article down a bit? For example: In the photograph that accompanies this article, how does one distinguish the three red keys from each other? Maybe I don't understand what "distinguish" means in this context? --Keeves (talk) 16:54, 19 August 2015 (UTC)
 * For the keys it is not just the colour, but also the position on the keyring relative to the other keys. Key 1 is red and next to one plain key on one side and two on the other (because it is a closed loop, Key 6 is on the other side of Key 1); Key 2 is plain and next to a red key on both sides; Key 3 is red and next to one plain key and one red key; Key 4 is red and next to one red key on one side and two plain keys on the other, etc. Any key you pick is in a unique sequence of coloured keys.

 * I added the sentence "With such a coloring, each key will be uniquely identified by the sequence of colors surrounding it." Does that help? —David Eppstein (talk) 17:40, 19 August 2015 (UTC)
