9/9 5 LED resistor exercise

Please locate the specs of 5 different LEDs on the one of the Digikey links. Each LED should be of a different color and manufacturer. Calculate what resistor using ohms law and a calculator would work for that LED. Please post to the blog. Include the manufacturer name and color.
