Maritime Signal Flags

The International Code of Signals is the alphabet of the sea — twenty-six letter flags plus numeral pennants, each a geometric arrangement of blocks, stripes, saltires and borders built from exactly five colors: red, yellow, blue, black and white. Those five were not chosen for beauty but for legibility: they hold their difference against open water, glare and grey sky at distance. Printed as a reference grid on a navy chart card, the flags become a study in functional contrast — flat color fields, crisp edges, no decoration that does not carry meaning.

《国际信号规则》是大海的字母表——二十六面字母旗加上数字旗，每一面都由色块、条纹、 斜十字和边框拼合而成，且只用五种颜色：红、黄、蓝、黑、白。这五色并非为了好看， 而是为了辨识：在开阔海面、强光与灰白天空之下，它们仍能在远距离上彼此分明。当它们 被印在深海军蓝的海图卡片上、排成参照网格时，便成了一场关于功能性对比的研究——平涂 色块、利落硬边，没有任何不承载意义的装饰。
