Hi Ariba,
I actually looked at the css to see if I could reach the color but in vain (my css skills are limited)... So I left the file as is.
Then, following your message, I looked at the template and clicked on 'Update settings'. After a few seconds, I checked but no change. There doesn't seem to be an update available for this template.
I ended up using your custom css which is exactly what I expected. I will wait for the next update of the template...
Congratulations to you and the team for the quality of your work.
