如何根据列表在kivy中生成6个彩色标签？

from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.boxlayout import BoxLayout
from kivy.utils import get_color_from_hex

class ColorLabelLayout(BoxLayout):
    def __init__(self, **kwargs):
        super(ColorLabelLayout, self).__init__(**kwargs)
        self.orientation = 'vertical'

colors = ['#FF0000', '#00FF00', '#0000FF', '#FFFF00', '#FF00FF', '#00FFFF']
for color in colors:
    label = Label(text='Color Label', color=get_color_from_hex(color))
    self.add_widget(label)

class ColorLabelApp(App):
    def build(self):
        return ColorLabelLayout()
