I found this technique previously on a Google search and adapted it
for my own purposes. Of course it depends on unsupported
implementation details of the Google Maps Flash API.
var map : com.google.maps.Map; // your map instance
var mapSaturation : Number; // 0 = completely transparent, 50 =
completely unsaturated, 100 = completely saturated
var mapLayerFilter : ColorMatrixFilter = new ColorMatrixFilter();
var matrix : com.gskinner.geom.ColorMatrix = new
com.gskinner.geom.ColorMatrix();
matrix.adjustSaturation(Math.max(0, 2 * (mapSaturation - 50))
- 100);
mapLayerFilter.matrix = matrix;
var mapSprite : Sprite = ((map.getChildAt(1) as
Sprite).getChildAt(0) as Sprite);
mapSprite.filters = [mapLayerFilter];
mapSprite.alpha = Math.min(1, 2 * mapSaturation / 100);
