Stamp Album recreates the working surface a collector actually sees: the near-black, bottle-green stockbook page where perforated stamps sit behind crystal glassine strips on jet archival card. It is the visual world of early-20th-century Western European philately — Stanley Gibbons catalogues, SAFE and Prinz stockbooks, brass loupes and gilt-stamped serif titling.
This system distills that culture into a dark, archival interface: bottle-green linen grounds, gilt catalogue rules, brick-red definitives, and engraved serif type set in ruled catalogue tables. The page is never cream paper — it is the black card the stamps are mounted on.
「集邮册」还原了集邮者真正面对的工作面：那片近乎漆黑、瓶绿色的插册页——齿孔邮票借玻璃纸晶条嵌在乌黑的档案级卡纸上。这是二十世纪前期西欧集邮文化的视觉世界——史丹利·吉本斯目录、SAFE 与 Prinz 插册、黄铜放大镜，以及烫金的衬线书名。
本设计系统将这一文化提炼为深色的档案式界面：瓶绿亚麻底色、烫金目录细线、砖红色普通邮票，以及排在带格目录表中的雕版衬线字体。页面绝不是奶白色纸张——而是邮票贴附其上的那张黑卡纸。
