From the website, how to do it:
To choose the color of our tree, just send a color to @tweet_tree on Twitter.
@tweet_tree red, green, purple, green, p, g, r, b
@tweet_tree understands red, orange, yellow, green, blue, and purple. Send one color, or combination of colors to morph through. Separate multiple colors with a comma. Only the first letter of the color matters, r,o,y,g,b, & p, are acceptable color commands.
@tweet_tree red, *ff0000, green, *00ff00, blue, *0000ff
You can also blend custom colors using 24bit hexadecimal color codes. Here’s a color picking tool to help you choose values. Send the value as *rrggbb, where rr=red, gg=green, and bb=blue. We used the * designator because the more common # is already used for Twitter hash tags.
