Scratch

Try using the color effect:

change [color v] effect by (25)
set [color v] effect to (25)

Well, unfortunately there's not a super fast way to do it, but I thought of a way that might be less tedious than your current solution. Instead of changing the colors of sprites, you could have one sprite that uses pen to draw the background. In turbo-mode, it works pretty quickly. Maybe this or a variation could do the trick. 

when I receive [Change Background v] //this can be whatever triggers your background change
clear
go to x: (-240) y: (180) //start in the upper left-hand corner
repeat (360) //the 2 repeats cycle through every x,y position on the stage. Outer is going down, inner is across
 repeat (480) //go across until it gets to the end
  set pen color to (distance to [Sprite1 v])
  pen down //color the pixel
  pen up 
  change x by (1) //move 1 to the right
 end
 set x to (-240) //now go back to the left end 
 change y by (-1) //and down 1 row
end
