I.8 Semester I Review 8

1. Make a 300x700 gradient that goes from “MediumVioletRed” at the top to “LimeGreen” at the bottom. Include at least three check-expects.

2. Create a function purple-ize: image -> image that takes in an image and changes every pixel’s color to the closest “purple” color.

   Say purple is red and blue, so the nearest purple color
   corresponds to whichever component has more.
   
   Example: the nearest purple color to (220,50,80) is
   (220,50,220), and the nearest purple color to (30,40,50) is
   (50,40,50).
   

Bonus: Animate a purple-izing circle of radius 20 that follows the mouse around an image.
