turtle.pensize(10)
turtle.bgcolor('black')
turtle.colormode(255)
turtle.speed(0)
turtle.delay(0)
turtle.penup()
turtle.sety(250)

c = (0,0,255)

for x in range(18):
    for s in range(45):
        c = coloradd(c,0.01)
        turtle.color(c)
        turtle.fd(12)
        turtle.rt(8)
    for w in range(45):
        turtle.pensize(3)
        c = coloradd(c,0.01)
        turtle.color(c)
        turtle.fd(10)
        turtle.rt(8)
        turtle.pensize(10)
    turtle.penup()
    turtle.fd(100)
    turtle.rt(20)
    turtle.pendown()
