I hear you, it’s always frustrating when you dislike something that many other people seem to enjoy. It happens to me with Star Wars, I can’t understand how people love that saga so much when I can barely stay awake while watching them (yeah, I’m ready to be hated right now 
).
We are totally aware that not everybody likes hot coral. And I’m pretty sure sooner or later we will give alternatives but for the time being we are focusing on offering just one option, the option that is granting us great feedback (easier to operate and cheaper to produce). We’re still very small, please keep that in mind. We push harder on the things that seem to work for us.
So, once we’ve decided to keep hot coral I think it just makes sense to polish the result and make it even better. In this case by removing the ugly white layers that, to be honest, were never part of the design but a side-effect of the status quo on how cards are typically manufactured. As we learn more we get closer to our idea of a perfect hot coral card.
The good news is that, by the time we offer other options, we’ll pour the same passion on making those cards as perfect as we think they can be. Hope it makes sense
