基于JS编写一个看字说颜色小游戏

// 定义设置颜色(12种颜色) 
let colorNameList = ['红', '绿', '蓝', '黄', '黑', '白', '灰', '紫', '粉', '青', '橙', '棕'];
// 对应颜色的十六进制
let colorHexList = ['#FF0000', '#00FF00', '#0000FF', '#FFFF00', '#000000', '#FFFFFF',
'#999999', '#9933FF', '#ff00cc', '#65ffcd', '#ffa500', '#D2691E'];
// 颜色对应的map形式
let colorMap = {
    '红': '#FF0000','绿': '#00FF00','蓝': '#0000FF','黄': '#FFFF00',
    '黑': '#000000','白': '#FFFFFF','灰': '#999999','紫': '#9933FF',
    '粉': '#ff00cc','青': '#65ffcd','橙': '#ffa500','棕': '#D2691E'
