What is a good way to give the appearance that a String of text is fading away?  How can I do this?

One way of going about it would be to draw the text on something (canvas or whatever) with different color starting with the inverse of the background and going to the background.  A number of colors you need to go through is determined by how fast you want the text to fade away.

How do I find the inverse of the background?

Could you provide a small example of how to do this?

How can I make this dynamic according to what color the text is, and what color the background is?  I don't want to hardcode anything in terms of colors.  I want it to all be dynamic depending on the colors being used.  How can I do this?

The easy way to figure out the inverse of a color is the following:

break the color into RGB components, say (red, green, blue) contain the values.  Then the inverse of the color is simply (255-red, 255-green, 255-blue).

Start up from here.

I am not sure if understand what you are trying to do though...I think what I am trying to do is I want to fade the Color of the graphics so that it eventually is the same color as the background of the Canvas.  So how would you do this with what you proposed?  Could you provide an example?
