Write a function to “blue-ify” a face. Write a function that accepts a picture as input. If any pixel has a blue value less than 150, then set that pixel’s color to white. Try it on a picture of a face and see what you get.

Question

What will be an ideal response?

Answer 1

```
def blueify(picture):
for pix in getPixels(picture):
value = getBlue(pix)
if value<150:
setColor(pix,white)
```

Note: If the picture is dark enough, checking for values less than 150 may lead to a mostly white image.
