  1. are these individual led's or packaged as a matrix
  2. common anode or cathode
  3. do you want to have 3 colors, or do you want to mix them
    3b) if your going to mix them how many possible colors

Good questions. I am just starting to learn about this stuff, so maybe you can help me with some of this, but here were my initial thoughts:

  1. I was thinking individual RGB LEDs. I was thinking something like http://www.sparkfun.com/commerce/product_info.php?products_id=105 Can I mix the colors with these LEDs to make, orange for example?

  2. Good question? I don't know enough yet. Could you help me with this one?

  3. I want to mix them so I create colors. So, I could do something like mix red and blue to get purple.

3b) Again, I'm not sure? Wouldn't that be up to the LED?

Thanks for all your help! I really appreciate it!
