how to send html email from shell script

Shell Programming and Scripting
1

This is my below script which is working fine as it send only plain text email.

So My question is- How can I modify my below script to send this as an HTML formatted email? I want to show the text color of this expression `(echo "100*$TEST2/$TEST1" | bc -l)` as `RED` in an email and that can be done only in HTML formatted emails. So that is the reason I was thinking to send an email in HTML formatted way. Any suggestions will be of great help.

 #!/bin/bash
    
    TEN_DAYS="3793274 230667"
    
    TEST1=`echo $TEN_DAYS | awk '{print $1}'`
    echo $TEST1
    
    TEST2=`echo $TEN_DAYS | awk '{print $2}'`
    echo $TEST2
    
    mailx -s "Report" -r uname@host.com uname@host.com <<EOF
    
    Error  Percentage: `(echo "100*$TEST2/$TEST1" | bc -l)`
    
    EOF
