Yes, this will be a series. The reason why there aren't 26 races (the number of letters on the alphabet) is because some of the letters have a very low number of colors (Z haves 4 colors, U and X have 2 each, Y and Q only have 1 each), so I'm grouping them with other letters. Also, there will be a final race featuring the winners of each race.
Results for this particular race will come soon.

1st: Apple Green
2nd: Antique White
