think:  
1注意细节（单词输入是否正确，花朵的颜色种类需要注意）  
2enum和switch的用法  
3enum集合内默认下标从0开始

简单枚举类型——植物与颜色  
Time Limit: 1000MS Memory Limit: 65536KB

Problem Description  
请定义具有red, orange, yellow, green, blue, violet六种颜色的枚举类型color，根据输入的颜色名称，输出以下六种植物花朵的颜色：  
Rose(red), Poppies(orange), Sunflower(yellow), Grass(green), Bluebells(blue), Violets(violet)。如果输入的颜色名称不在枚举类型color中，例如输入purple，请输出I don’t know about the color purple.

Input  
输入数据有多行，每行有一个字符串代表颜色名称，颜色名称最多30个字符，直到文件结束为止。

Output  
输出对应颜色的植物名称，例如：Bluebells are blue. 如果输入的颜色名称不在枚举类型color中，例如purple, 请输出I don’t know about the color purple.

Example Input  
blue  
yellow  
purple

Example Output  
Bluebells are blue.  
Sunflower are yellow.  
I don’t know about the color purple.

Hint  
请用枚举类型实现。
