Color Models

You can animate the background color, text color and shadow color of a layer. By default, color transitions use HUSL. With the colorModel property, you can specify in which model to animate. We support rgb, hsl and husl.
译：你可以给图层的背景颜色、文字颜色和阴影颜色添加过渡动画。通常情况下颜色过渡使用HUSL格式的色值。你可以通过colorModel属性来指明需要通过哪种方式过渡，支持rgb、hsl和husl。

    backgroundColor: "blue"

# Animate in RGB 
bg.animate
    properties:
        backgroundColor: "red"
