# 颜色格式

AWTK 目前支持以下颜色格式：

* 十六机制格式。

RGB 三个通道分别用两个十六进制的字符表示，alpha 通道为 0xff（即不透明）。如：

``` 
#ffeedd 表示 R、G、B 分别为 0xff、0xee、0xdd
```

* rgb(R,G,B) 格式。

括号中的 R、G、B 为 0 到 255 之间的十进制数，alpha 通道为 0xff（即不透明）。如：

```
rgb(100, 150, 200) 表示 R、G、B 分别为 100、150、200 
```

* rgba(R,G,B,A) 格式。

这是唯一支持半透明颜色的方式。

括号中的 R、G、B 为 0 到 255 之间的十进制数，A 的为 0 到 1 之间的小数。如：

```
rgba(100, 150, 200, 0.5) 表示 R、G、B, A 分别为 100、150、200、0.5
```

> 注意：半透明颜色填充相对于不透明颜色填充，要慢很多，请谨慎使用。

* 英文名称。目前支持的颜色名称有：
