No,  there is not, unfortunately.

Here is a colored figure attached for the different LEDs forward voltages in the function of their forward current, from the link: http://www.maxim-ic.com/appnotes.cfm/appnote_number/1883

White LED is not shown, it has an average 3.1 -- 3.2V drop for a 15-20mA forward current, just a bit less than for the blue LED.

So the red LED has the smallest drop of around 1.5V.
