Question

create anything in python. Make sure your code covers all of the following things: • Use the concepts of object-based programming—classes, objects, and methods • Draw two-dimensional shape • Use the RGB system to create colors in graphics applications and modify pixels in images • Develop recursive algorithms to draw recursive shapes • Write a nested loop to process a two-dimensional grid • Perform simple transformations of images, such as conversion of color to gray-scale

imageGraphicsError: bad color sequence: (255, 40, 5)

to change the color mode of the image, then it works:

image.colormode(255)
image.color(255, 40, 5)
