Generate a Random Color Java

I am trying to create a random color by randomly generating numbers for R,G, and B values with a random number generator, and using the values to make a color. The following code is in my onCreate() method:

Random rand = new Random();
    // Java 'Color' class takes 3 floats, from 0 to 1.
    float r = rand.nextFloat();
    float g = rand.nextFloat();
    float b = rand.nextFloat();
    Color randomColor = new Color(r, g, b);

How come eclipse tells me "The constructor Color(float, float, float) is undefined"? Shouldn't this work correctly?
