When I add the tape for two, exactly one of these uncolored squares gets a color. Thus this solution is different from my other solution where all squares get at least one and at most finitely many different colors. (It does resemble the explicit example posted by Achim Krause.) However, I find this exposition even more appealing. Gerhard "Math Is In The Telling" Paseman, 2018.01.02. | |
