Please help I wrote this code to just filter over an image not completing turn it the color blue red or green. How do I have the code filter the image and still show the image but with a red filter or green or blue. thank you

# Constants for the image
IMAGE_URL = "https://codehs. com/uploads/c709d869e62686611c1ac84 9367b3245"
IMAGE_WIDTH = 420
IMAGE_HEIGHT = 300
IMAGE_LOAD_TIME = 1000

image = Image(IMAGE_URL)
image. set_size(IMAGE_WIDTH, IMAGE_HEIGHT)
add(image)

# asks the user to input a color of choice

user_color = input("Pick a color, blue, red or green:")

red = 255
green = 0

if user_color == "green":
red = 0
green = 255
blue = 0

if user_color == "blue":
red = 0
green = 0
blue = 255

def custom_filter(image):
for x in range(image. get_width()):
for y in range(image. get_height()):
image. set_blue(x, y,blue)
image. set_red(x, y,red)
image. set_green(x, y,green)

return image

def change_image():
global image
image = custom_filter(image)

timer. set_timeout(change_image, IMAGE_LOAD_TIME)
