As per title. When I change the background color of the whole canvas to something like #000000 it gets saved and displayed as #000000FF. This is fine but when I open this e-mail in Outlook the background color is missing. By changing the code of an e-mail so that all #000000FF are replaced with #000000 it gets displayed.
After seeing this I wanted to simply set it to #000000 but it isn’t possible as all color formats on the color selection modal are the ones that include transparency (HEXA, RGBA and so on).
