using a blend mode to shift hue of all sprites

Is it possible to shift the hue of all sprites by drawing a rectangle over the view and then using some kind of blend mode to shift the hue of everything? I can make a bunch of cool stuff with the various blend modes, but nothing pertaining to the hue of sprites specifically. Any pointers?

Thanks to all who reply

You could use the blend action with all objects.

Umm..... I don't think this is possible.... (It mite be with a DLL.) Why do you wont this ?

Though... what exactly do you meen by hue ? do you meen color? or....?
Edit:
what about this

Code:

with(all){image_blend=c_blue}

The idea is to basically achieve what was done in older arcade games. When a certain number of waves (or whatever) is achieved the background (in my case everything) shifts it's hue to another color. Hue is kinda hard to define, but basically all the colors shift down the color wheel, no colors are lost, just changed. You can find the wikipedia definition here and here's an animated example of the hues being shifted all the way down the spectrum:





Thanks for your help!

You just make multiple sprites. All with different hues
Of course that would take a long time.
Wouldn't changing the color for the "draw_spr_ext" function work as well?
Example: to make it blue change the color part from "c_white" to "c_blue"

But he doesn't wont to just change the color to 1 thing, he wont to... I cant explain, did you read the thing above ?

Yes, I understand. It doesn't do it the way he wants it to because he would have to do it for each individual things, but it does get the job done

I've determined that a "shift hue" blend effect isn't possible with GM. I greatly appreciate the effort though! Thank you all!

John,
