I've been trying to scratch my head through this most of the day, and I seem to be running in circles.
I know I shouldn't edit the default email templates at all (and I'm cool with that). I've found the default templates in
Vendor > Magento > theme-frontend-luma > web > css > source. However, I cannot see anywhere where the colors of this theme are specified.
I don't want to change the layout of the email templates, but I just want to change the default colors (and the logo obviously).
How/Where do I create my own email template theme that doesn't interfere with the actual website theme ?
Thanks in advance
