如何在Write-Host中为颜色使用十六进制代码？

$color = "#FF0000"  # 十六进制颜色代码，表示红色

# 提取RGB值
$r = [int]('0x' + $color.Substring(1, 2))
$g = [int]('0x' + $color.Substring(3, 2))
$b = [int]('0x' + $color.Substring(5, 2))

# 构建Escape字符序列
$escapeSequence = "\e[38;2;$r;$g;$b" + "m"

# 输出带有颜色的文本
Write-Host -NoNewline $escapeSequence
Write-Host "这是红色的文本"
Write-Host -NoNewline "\e[0m"  # 恢复默认颜色
Write-Host "这是默认颜色的文本"
