One other thing to remember is that LED's of different colours will have a different brightness even though their MCD rating may be the same. This is because a lot of the light emitted by an LED may be out of the visible range. The best example is to compare a 20,000MCD red LED against a 5000MCD blue LED... The blue LED appears brighter than the red because a lot of the light from the red LED is out of the visible range (e.g. Infra Red)

This is incorrect.
LEDs are monochromatic (sp?), which means that it only produces one wavelength (shade) of light.
Some colors look brighter than others because our eyes dont see all shades of light at the same level.
