Change the Colour of a value in a SQL Server DB Mail - html

Question

I have created a DB Mail alert that sends out a HTML formatted table showing the pass or fail status of my SQL agents.
The alert works well, but the user has request an additional change where they want conditional formating on Pass/Fail status of the data, where failed status is to be highlighted RED and pass status to be highlighted GREEN.
Is this possible to achieve to in SQL using DB Mail and HTML formatting?
A few forums have stated that JavaScript may need to be used but I'm not sure if its possible to even us JS in SQL.
My code is below:

Declare #email_body nvarchar(max)
Declare #email_profile_name nvarchar(max)
Declare #email_recipients nvarchar(max)

I hope the code is clear enough and makes sense.

I do something similar with my dbmail audit emails to differentiate between production and non-production instances.
The method I use is to predefine the style information and then use a unique value in the body string to identify where the style needs to be applied. In your case the unique values we can use are <td>Failed and <td>Succeeded. By doing a replace on those values to a version that includes the style, you should get a table with your conditional formatting.
I made the following two changes to your script and ran it against one of my test instances. It looks like it should get you where you want.
First, update the style section:
--Set Style (CSS)
SET #Style += +N'<style type="text/css">' + N'.tg {border-
collapse:collapse;border-spacing:0;border-color:#aaa;}'
+ N'.tg .green{background-color: green; color:white;}'
+ N'.tg .red{background-color: red; color:white;}'
+ N'.tg td{font-family:Arial, sans-serif;font-size:14px;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:#aaa;color:#333;background-color:#fff;}'
+ N'.tg th{font-family:Arial, sans-serif;font-size:14px;font-weight:normal;padding:10px 5px;border-style:solid;border-width:1px;overflow:hidden;word-break:normal;border-color:#aaa;color:#fff;background-color:#f38630;}'
+ N'.tg .tg-9ajh{font-weight:bold;background-color:#68cbd0}' + N'.tg .tg-hgcj{font-weight:bold;text-align:center}'
+ N'</style>';
After #tableHTML is built, add a REPLACE to shove the style formatting into the generated table:
SELECT #tableHTML = REPLACE(REPLACE(#tableHTML,N'<td>Failed',N'<td class="Red">Failed'),N'<td>Succeeded',N'<td class="green">Succeeded')
