[Question] upper half circle

Question

I can create a bowl-like bottom semicircle on canvas as code. However, it is difficult to create a rainbow-like upper semicircle. How can I make it?

Code sample

import math

import flet as ft
import flet.canvas as cv

def main(page: ft.Page):
    stroke_paint = ft.Paint(stroke_width=2, style=ft.PaintingStyle.STROKE)
    fill_paint = ft.Paint(style=ft.PaintingStyle.FILL)
    cp = cv.Canvas(
        [
            cv.Arc(65, 65, 70, 70, 0, 3.14, paint=stroke_paint),
            cv.Arc(50, 50, 100, 100, 0, 3.14, paint=stroke_paint),
        ],
        width=float("inf"),
        expand=True,
    )

    page.add(cp)

ft.app(main)
