$a = ""
$a = $a + "BODY{background-color:#95B9C7;font-family:Calibri;font-size:10pt;}"
$a = $a + "TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}"
$a = $a + "TH{border-width: 1px;padding: 0px;border-style: solid;border-color: black;background-color:thistle}"
$a = $a + "TD{border-width: 1px;padding: 0px;border-style: solid;border-color: black;background-color:palegoldenrod}"
$a = $a + ""
Get-Diskinfo | ConvertTo-HTML -Head $a | out-file c:\Scripts\DCs.htm

Above code is working fine. Want to add Color Red when False becomes True on Lowspace.

I’d suggest looking at our free eBook, “Creating HTML Reports in PowerShell.” I wrote a module that makes this kind of conditional formatting easier, and the ebook contains an example of exactly that. You’ll also have to do a lot less manual HTML creation like you’re doing - my module handles most of it, with a lot of dynamic display options.
