I tried to use ColorReplace to change the colors obtained from MorphologicalComponents. However some of the changes didn't follow the rules specified, Is there any reasons?

im2 = Binarize@Import["https://i.sstatic.net/ZDeYq.jpg"];
im3 = Colorize@ MorphologicalComponents@im2 
colors = DominantColors[im3, 5]

enter image description here

Now trying to change the colors accordingly,

ColorReplace[im3, {
  colors[[2]] -> Red, 
  colors[[3]] -> Blue, 
  colors[[4]] -> Green, 
  colors[[5]] -> Yellow
  }]
