Set intensity of Color Object

Question

Hello All,
I am wondering if there is a was of settin the intensity of a Color object. I have a list of decimal numbers ranging from 0-1 and need to set the color object to white (if number is 0) or black (if number is 1) and grey in between 0-1. However, the intensity or depth of the color grey is to be defined with the value of the decimal number i have.
Does anyone know a way in which i can do this??

I would like to know the same thing, but I'm not sure how to do it either, and I don't quite understand the replies to the original post. I want to set the color (and size, but I figure once I can do the color, I can figure out the other) of an object based on another variable's value (that value can go from 1-100). Say that I want it to go from really dark green to really light green (but never all the way to black or white). Isn't there some kind of 128 or 236 colorscale that I can pick a range from or something? How would i do this?
  public void updateVertexAppearance() {
       //update vertex appearance, changing the size and color based on power.
            this.setColor(java.awt.Color.Something);//some kind of scale here based on power (1<=power<=100).
            this.setHeight((int) Math.round((power + 2)/5));//min/max is 1/20
            this.setWidth((int) Math.round((power + 2)/5));//min/max is 1/20
  }
