Color System

The Widget objects in Newcar can be set to any color you like, managed by the Color object. Currently, there are three ways to set colors, and in future versions, we will introduce gradients and other color features.

Direct Reference

This method can only support two colors - black and white.

const rect = new Rect([0, 0], [100, 100], {
  style: {
    fillColor: Color.WHITE,
    border: true,
    borderColor: Color.BLACK
  }
})

Using Color Name Strings

const RED = Color.parse('red')

Color name string parsing supports all color names supported by CSS.

RGBA

Color.rgba(255, 255, 255, 0.5)

Transform

You can transform the Color object as a variety of forms.

toString()

You can use this function to transform a Color into css color string.

toFloat4()
