颜色
React Native 中的组件是使用 JavaScript 进行样式化的。颜色属性通常与 Web 上的 CSS 工作方式相匹配。每个平台上关于颜色使用的一般指南如下：
颜色相关的 API
React Native 有几个颜色 API，旨在让您充分利用平台的设计和用户偏好。
- PlatformColor 允许您引用平台的颜色系统。
- DynamicColorIOS 是 iOS 特有的，可以让您指定在浅色或深色模式下使用哪些颜色。
颜色的表示形式
红-绿-蓝 (RGB)
React Native 支持 rgb() 和 rgba() 两种十六进制与函数方法
'#f0f'(#rgb)'#ff00ff'(#rrggbb)'rgb(255, 0, 255)''rgba(255, 255, 255, 1.0)'
色调-饱和度-亮度 (HSL)
也支持 hsl() 和 hsla() 函数方法：
'hsl(360, 100%, 100%)''hsla(360, 100%, 100%, 1.0)'
颜色值
React Native 还支持将颜色表示为int值（以 RGB 颜色模式）：
0xff00ff00(0xrrggbbaa)
注意
这看起来可能与 Android Color 的整数表示类似，但在 Android 上的值是以 SRGB 颜色模式（0xaarrggbb）存储的。
全透明 transparent
全透明颜色值rgba(0,0,0,0) 有个单独的写法，和CSS3一致：
'transparent'
颜色名称
你还可以使用颜色名称来作为颜色值. React Native 遵循CSS3 规范：
