被涂满红色的英文可以用 "covered in red" 来表示。

"Covered" 这个词的意思是被覆盖或包裹，而 "in" 是介词，表示在某个地方。所以 "covered in red" 的意思就是被涂满红色。

下面是一些例句：

The wall was covered in red graffiti. (墙壁上被涂满了红色的涂鸦)
The streets were covered in red leaves during autumn. (秋天的街道上遍布着红色的树叶)
She had a red scarf covered in snowflakes. (她戴着一条带有雪花图案的红色围巾)

注意，"covered in red" 只能用来描述被涂满红色的东西，而不能用来描述人。如果要表示人脸被涂满红色，可以用 "covered in red paint" 来表示。

例如：

He had his face covered in red paint for the carnival. (他在狂欢节期间脸上涂满了红色的油漆)
