Slightly modify the slanted fractal tree to make the color of the branch lighter as the branch gets thinner. Also slightly modify the slant angles.
Source Code:
import turtle
screen = turtle.Screen()
screen.title('Slanted Fractal Tree - PythonTurtle.Academy')
screen.setup(1000,1000)
screen.setworldcoordinates(-1000,-1000,1000,1000)
screen.tracer(0,0)
turtle.speed(0)

turtle.seth(direction)
turtle.pensize(length/50)
turtle.color((0.5-length/L*0.5,0.5-length/L*0.5,0.5-length/L*0.5))
