If condition in mail body phpmailer

I am using Phpmailer and I am currently emailing the data from my database. However, I need to have a color coding depending on the chosen condition. For example, if the remarks is proceed, the data cell should be in green color and red if hold. Im not really sure how to apply if loop inside an echo. Please help

while ($rowwaf = mysqli_fetch_assoc($queryres)){
$mailbody = "
        Good Day!<br><br>

        <strong>Details:</strong><br><br>

    -- if condition sample--
    if {
    $rowwaf["remarks"] == proceed
    <td style="color: green">".$rowwaf["remarks"]."</td></tr>
    }
    else {
