some LED resistances

Dialight, clear amber: 20mA, 1.9V forward voltage; with 5V supply, you need a 155 ohm resistor.

Avago Technologies, diffused blue: 30mA, 3.4V forward voltage; with 5V, you need a 53 ohm resistor.

Toshiba, clear green: 20mA, 2.1V forward voltage; with 5V supply, you need a 145 ohm resistor.

Lumex, red: 120mA, 2.4V forward voltage; with 5V supply, you need a 21.6 ohm resistor.

Rohm, white: 100mA, 3.8V forward voltage; with 5V supply, you need a 12 ohm resistor.
