If you're looking for something that provides selective color coding, then try something like this.

First, set up a helper function to select an appropriate color:

function Get-LogColor {
    Param([Parameter(Position=0)]
    [String]$LogEntry)

    process {
        if ($LogEntry.Contains("DEBUG")) {Return "Green"}
        elseif ($LogEntry.Contains("WARN")) {Return "Yellow"}
        elseif ($LogEntry.Contains("ERROR")) {Return "Red"}
        else {Return "White"}
    }
}

Then execute a line that looks like this:

gc -wait $logFile | ForEach {Write-Host -ForegroundColor (Get-LogColor $_) $_}

Try

Get-Content $logFile -Wait |
  Select-String $searchTerm | 
  ForEach {write-host -ForegroundColor red $_.line}
