    td {border-width: 1px; padding: 3px; border-style: solid; border-color: black;}
  
    }
    
    </style>
    "@
    
           
    $result = foreach ($ThisUser in $cInCsv) {  
        
        $EndDate = Get-Date ($ThisUser.'bitis')
        $licence = (New-TimeSpan –Start $StartDate  –End $EndDate).Days
        $ThisUser | Select-Object product,bitis, @{Name='gun'; Expression={$licence}}
           
        if($licence -lt 90 -and $licence -gt 0) {

            $ThisUser | Select-Object product,bitis, @{Name='gun'; Expression={$licence}} 
               
        }
        elseif ($licence -lt 0){
            $pos = [Math]::Abs($licence) 
            $ThisUser | Select-Object product,bitis,@{Name='gun'; Expression={$licence}}
        }
    }
    $result | ConvertTo-Html -Head $header | Out-File "C:\Users\akilic\Desktop\health.html"

Ok, in this case you can manipulate the HTML like below:

Change your $header variaable into this to add three class definitions:

$header = @"
<style>
table {border-width: 1px; border-style: solid; border-color: black; border-collapse: collapse;}
th {border-width: 1px; padding: 3px; border-style: solid; border-color: black; background-color: #6495ED;}
td {border-width: 1px; padding: 3px; border-style: solid; border-color: black;}
.redgun    {background-color: #ff0000; text-align: right;}
.yellowgun {background-color: #ffcc00; text-align: right;}
.greengun  {background-color: #33cc00; text-align: right;}
}
</style>
"@

Then change the final line of the code into:

$html = switch -Regex ($result | ConvertTo-Html -Head $header) {
    '<td>(-?\d )</td></tr>$' {
        $gunValue = [int][regex]::Match($_,'(?i)<td>(-?\d )</td></tr>$').Groups[1].Value
        if ($gunValue -gt 90) { $cell = '<td >' }        # red
        elseif ($gunValue -lt 0) { $cell = '<td >' }  # yellow
        else { $cell = '<td >' }                       # green
        # replace that part of the string to insert the class
        $_ -replace '<td>-?\d </td></tr>$', ('{0}{1}</td></tr>' -f $cell, $gunValue)
    }
    default { $_ }
}

$html | Out-File "C:\Users\akilic\Desktop\health.html"

Output:

If you don't want the single cell to have a different background color, but instead color the whole row, do this:

$header = @"
<style>
table {border-width: 1px; border-style: solid; border-color: black; border-collapse: collapse;}
th {border-width: 1px; padding: 3px; border-style: solid; border-color: black; background-color: #6495ED;}
td {border-width: 1px; padding: 3px; border-style: solid; border-color: black;}
.redgun    {background-color: #ff0000;}
.yellowgun {background-color: #ffcc00;}
.greengun  {background-color: #33cc00;}
}
</style>
"@

$html = switch -Regex ($result | ConvertTo-Html -Head $header) {
    '<td>(-?\d )</td></tr>$' {
        $gunValue = [int][regex]::Match($_,'(?i)<td>(-?\d )</td></tr>$').Groups[1].Value
        if ($gunValue -gt 90) { $row = '<tr >' }        # red
        elseif ($gunValue -lt 0) { $row = '<tr >' }  # yellow
        else { $row = '<tr >' }                       # green
        # replace the string to insert the class
        $_ -replace '^<tr>', $row
    }
    default { $_ }
}
