Change the colour of your object with the fill command
In this example we have added the fill command after the coordinates to change colour.
Flashing Colours
you will need to import random at the top for this to work
blob2=win.create_rectangle(150,150,200,200, fill="red")
col=["red","blue","green"] #create a list of colours
blob2=win.create_rectangle(150,150,200,200, fill="red") #create rectangle in blob2 variable
for i in range(60): #60 repeat loops
win.move(blob2,0,-2) #move blob2 -2 on y axis
changecol=random.choice(col) #make a random choice from col list and put it into changecol variable
win.itemconfig(blob2, fill=changecol) #update blob2 with new random choice colour
tk.update() #update the window
time.sleep(0.05) #short time delay to slow things down
Remember this will only work if it inside a canvas with mainloop at the bottom
