2. 自定义颜色

修改 ./src/theme/variables.scss 中

$colors: (
    primary:    #488aff,
    secondary:  #32db64,
    danger:     #f53d3d,
    light:      #f4f4f4,
    dark:       #222
);

可添加新颜色，如下：

twitter:( 
    base: #55acee, 
    contrast: #ffffff 
) 

base 作为元素背景色，contrast 作为文本颜色
在 html 中的使用如下：

<button ion-button color="twitter">I'm a button</button>

在 scss 中的使用如下：

my-component {
    background: color($colors, twitter, base);
}

3. 平台样式
