Six is a beautiful shade of dark blue. Sometimes 6 is silvery, too. Sixes are most beautiful when they are together. 66, 666, .66. They are the ocean waves. A six is a sleeping cat.
A six makes any other number seem cooler. The quiet, pale 7 becomes a rockstar when 67, because sixes are cool and mysterious and sexy. Don't even get me started on how sexy an awkward 9 becomes when with a 6.
Yet, sixes are comforting as well, a tire swing to play in, a mothers arm holding her baby. 6 is balanced and grounded. A 6 might roll around a bit, but a six won't fall like a 7 or a 9.
Sexy six is a much better number than that ugly, old, pee-yellow 8.
This is the approximate color scheme of a 6. It's a bit more shiny that that, though. It was the closest I could find in quick google search.
This is also a good example of the color six.
