The functions to create a tint or shade for a color have a paramater amount. Currenly this is the library code ``` TinyColor tint([int amount = 10]) { return this.mix(input: Color.fromRGBO(255, 255, 255, 1.0)); } TinyColor shade([int amount = 10]) { return this.mix(input: Color.fromRGBO(0, 0, 0, 1.0)); } ```
