Switching color of light

Question

I am rather new to Unity, and I was wondering how to smoothly change the color of a light in the Update function. I have tried a few variations of code based on Color.Lerp, but whenever I would, my colors would shoot up to an extremely high number. I don't have that code on me, but it was along the lines of:

 light.color = Color.Lerp(colorA,colorB,Update)

colorA and colorB are your basic colors, and Update ranged from Time.time to Time.deltaTime mixed with other variables to try to get increment from 0 to 1.

What can I do to get the colors to fade from one to the other?

Here's one approach. I haven't compiled the code so not sure if it contains spelling errors.

 var colorA : Color;
 var colorB : Color;
 
 function DoLerp (duration : float) {
    var startTime = Time.time;
    while (Time.time - startTime < duration) {
       var amount = (Time.time - startTime) / duration;
       light.color = Color.Lerp (colorA, colorB, amount);
       yield;
    }
    light.color = colorB;
 }
 @script RequireComponent (Light)
