Start with a picture of someone you know and make some specific color changes to it:

Question

• Turn the teeth purple.
• Turn the eyes red.
• Turn the hair orange.

Answer 1

Of course, if your friend’s teeth are already purple, or eyes red, or hair orange, choose a different target color.

```
def monsterify(picture, teethStartX, teethStartY, teethEndX, teethEndY, teethColor,
teethDistance, eyesStartX, eyesStartY, eyesEndX, eyesEndY, eyesColor, eyesDistance,
hairStartX, hairStartY, hairEndX, hairEndY, hairColor, hairDistance):
for px in getPixels(pic):
x = getX(px)
y = getY(px)
if (teethStartX <= x <= teethEndX) and (teethStartY <= y <= teethEndY):
if (distance(teethColor,getColor(px)) < teethDistance):
setColor(px,makeColor(255,0,255))
if (eyesStartX <= x <= eyesEndX) and (eyesStartY <= y <= eyesEndY):
if (distance(eyesColor,getColor(px)) < eyesDistance):
setColor(px,red)
if (hairStartX <= x <= hairEndX) and (hairStartY <= y <= hairEndY):
if (distance(hairColor,getColor(px)) < hairDistance):
setColor(px,orange)
```

Note: The solution above will work for any image, but could easily have been tailored to a specific one given the way the question was stated.
