Can I change snake's color?

Yes, you can change the snake's color by modifying the color value in the draw_snake function.

In the provided code, the snake is drawn using the color defined as GREEN. You can change this to any color you prefer by updating the pygame.draw.rect line in the draw_snake function.

For example, if you want to change the snake's color to red, you can do the following:

def draw_snake(snake_block_size, snake_list):
    for x in snake_list:
        pygame.draw.rect(screen, RED, [x[0], x[1], snake_block_size, snake_block_size])

Make sure to define the RED color at the beginning of your code if you haven't already:

RED = (255, 0, 0)

Feel free to choose any RGB color values you like! If you need help with specific colors, let me know!
