Using ColorMatrixFilter to tint to white and back to normal

[wograebn]

I would like to make an image go from normal -> fully white -> back to normal. Imagine for example shooting at an enemy in a game, and you want them to flash white briefly. I'm trying to use ColorMatrixFilter for this.

This will make the image show up as normal

colorMatrix = [
    1, 0, 0, 0,
    0, 1, 0, 0,
    0, 0, 1, 0,
    0, 0, 0, 1
  ];

This will make the image show up as fully white

colorMatrix = [
    1, 1, 1, 0,
    1, 1, 1, 0,
    1, 1, 1, 0,
    0, 0, 0, 1
  ];

My problem is blending inbetween, when the blend is halfway the image appears desaturated. Any way I can use colormatrixfilter to achieve the effect I am after?
