과학 인포그래픽: 여섯 가지 차의 계단

Infographic poster presenting the six major types of tea arranged by fermentation level, front-view flat presentation. Layout: a horizontal spectrum bar running across the poster from left to right showing white tea (unfermented), green tea (0%), yellow tea, oolong tea (10-70% partial fermentation), black tea (full fermentation) and dark fermented pu-erh tea, each with a circular illustration of its dry leaf and brewed liquor color in a small cup, plus a data badge with oxidation percentage, brewing water temperature and steeping time. A gradient arrow above the bar runs from pale silver-green to deep amber-brown, and small flat icons of the tea leaf, thermometer, hourglass and cup appear at each station. Color system: fresh tea greens (#7CB342, #33691E) shifting through golden yellow (#F9A825) to deep brown (#5D4037), on an off-white background (#FBF7F0). Typography: elegant serif for tea names, clean sans-serif for data labels, clear hierarchy. Background: subtle dry-leaf texture with faint tea-stain rings. Data feel: tea-master reference chart with precise oxidation numbers. Lighting: warm soft light from the upper left, glossy cup highlights, gentle shadows. 4k
