The closest you can get is to paste the Sprite to a canvas object, read the pixels, calculate the tint then draw it back. This isn't fast at all so maybe you could do it when the game starts and draw by juggling the canvas objects.
Another way would be to use blend modes to color the objects, however you can't exactly do a tint.
Anyway to do this it's probably easiest to use the canvas or paster objects, although you may be able to do it with layers instead.
Basically each Sprite will have a paster object positioned over it so the paster covers the Sprite. Then do these steps
Fill paster with whatever color you want.
Set the sprite's blend mode to source in.
Paste Sprite to paster
Set the sprite's blend mode to normal
Then you just adjust the opacity of the paster object to change the strength of the coloring. You could also use the additive blend on the paster object for a different coloring.
Keep in mind each instance of canvas/paster will use it's own texture.
