On the one hand, I understand where you’re coming from with the apparent brand inconsistency.
On the other hand, the hot coral card is a massive selling point. It’s the single most visible thing that says “we’re different from other banks” and catches people’s interest. Catch their interest first, then you can sell them on what Monzo is and how it works (source: me. I went from “woah, what’s that?” to “this could be useful for my needs”)
I am, therefore, very much in the camp that thinks the cards should still be hot coral after the current account roll-out. But I wonder how they’d look if, instead of having ‘monzo’ in white text, they had the app logo. Perhaps that would be a way of tying things together without losing anything.
Regarding the issue Kylemonk had, I think that’s partially down to the pre-paid cards having no names on, and will be less of an issue when the current account cards are rolled out.
