You can also do this using a Lerp function. There's one in XNA, but it's easy to write yourself.

See my answer to this similar question for a C# implementation.

The function lets you do this:

// make red 50% lighter:
Color.Red.Lerp( Color.White, 0.5 );

// make red 75% darker:
Color.Red.Lerp( Color.Black, 0.75 );

// make white 10% bluer:
Color.White.Lerp( Color.Blue, 0.1 );
