Apply company branding to webparts in Outlook emails

Hi,

We are having issues with Outlook emails pulling through company branding from Viva Amplify.

We can customise the Outlook channel to edit the email output (i.e. changing the background colour of sections), but are struggling to change the colour theme for buttons - the buttons default to a blue theme and can't be changed.

I am aware that the Brand Center may soon be able to work with Viva Amplify Outlook emails. Will the Brand Center allow company colours to be applied to webparts such as buttons?

Thanks,
Jake
