Each sushi piece is perfectly wrapped in tag pairs, has text as sushi rice, and attributes marked by spam or Mackerel or tuna... yeah... messed up.
May be the roasted Hojicha can be think of as Orange in flat, but Gyokuro is almost as green as Sencha right? So why the color? But indeed it is pretty. Functional?
Debatable, but does give a quick cue.
The typography shouts a clear message though! It's a Teabag!! Just kidding. The Tea names are pretty easy to read. Not sure why the tea bag sign is so obvious. One bonus point on Japanese-style details: the tea word is completely redesigned with the english letters blent into Kanji
But just like many flat UI, it is vibrant, beautiful, HAPPY, and easy-to-read, yet not functional enough to tell me anything about the tea yet. The elaborate diagram below only explains why tea bags are important and convenient... yeah we know.
