Increase # of colors!

Experiment showed that my math was wrong and I was missing an entire index of color!

(0...256).map { |n| [n, n * 6 / 256] }
         .group_by(&:last)
         .each { |k, v| puts "#{k} - #{v.size}" }

# >> 0 - 43
# >> 1 - 43
# >> 2 - 42
# >> 3 - 43
# >> 4 - 43
# >> 5 - 42

Fixed it, it adds a lot!
