#declare MaxWidth = 320; // Or whatever the imagewidth is
#declare MaxHeight = 180; // Or whatever the height is

// You'll need to determine these values from the original images
#declare LowerColLimit = 0.45;
#declare HighColLimit = 0.55;


#local PIMAGE = function {
pigment{image_map {"mario.png"}
rotate x * 90  // rotate backwards
translate < -0.5, 0, -0.5 > // slide over so the center is on <0,0,0>
scale <MaxWidth,1,MaxHeight>//scale to image size
}}

#declare CountH = -div(MaxWidth,2);
#while (CountH< div(MaxWidth,2))
  #declare CountV = -div(MaxHeight,2);
  #while (CountV< div(MaxHeight,2))
    #declare COL=PIMAGE(CountH,1,CountV);
    #if ((COL.blue < LowerColLimit) | (COL.blue > HighColLimit))
      object {LegoBlock pigment { Col } translate <CountH,2,CountV>}
    #else
      object {LegoBlock pigment { SkyBlue } translate <CountH,1,CountV>}
    #end
  #declare CountV = CountV + 1;
  #end
  #declare CountH = CountH + 1;
  #end

This is untested code but it should work
