How can I control colorduino with button

When I connect TX and RX between arduino uno and colorduino
I need to switch to “Arduino Duemilanove” on Arduino IDE
But there is no any reaction on the button

If i try to use the “Arduino Uno” on Arduino IDE for uploading code
There are errors
I search for reason and people said it cannot plugin RX and TX on arduino uno

Is it possible to use button control RGB Led with colorduino on arudino uno?
