Which backlight colour is the most effective?

I've got a pushbike clock/speedo im planning on adding to my bike, however im undecided as to what colour backlight to put in it, im leaning towards white and blue due to availability of the LED's, especially the white ones. Amber would be neat, considering the display on my bike is mostly orange, but its just a shame they don't have 3mm LED's (very tight space im fitting this in) in orange, only 5mm ones.

Oh and im not just after appearances, but mostly which do you think would be the most visible at night/daytime?

Amber


White


Blue


Red


Green

If you want good daytime viewing go the best contrast you can get. Either normal LCD black on grey, or black on white imho

Always had a soft spot for the Blue... (Takes me back to my old Nokia 8250)

hehe 8250, the one you dredded getting out at the movies or anywhere dark, everyone was blinded!!!


go the blue mike

Id go red or blue i think they are easy to see through a tinted V at night.
