Ruby - These pieces are a vibrant ruby red, with the "eyes" of the wood retaining some their original tan maple color.
Emerald - Ranging from a deep emerald to a turquoise, these have very little of the tan-colored eyes, with more emphasis on the marbling.
Royal Purple - In most of the purple pairs, the dye has covered the "eyes" of the wood, leaving only specs of tan within the rich swirls of purple.
Red/Purple - Dyed using two colors, these pieces are more complex than the single colored pieces, and still retain a moderate amount of the tan "eyes."
Green/Purple - With varying amounts of dye, some pieces are more purple, while others are more green, and the number of "eyes" that remain intact changes from piece to piece.
Black - The darker dye causes some of the stripes to turn a dark black/grey, emphasizing a more striped look to the wood.
Red/Black - Swirling with two deep tones, the red and black create a very marked battle between two rich colors.
Emerald/Black - Primarily black, this pair has deep swirls of green that create a mysterious allure.
