ICS Uniform (International Code of Signals) Holographic STICKER Die-Cut Vinyl Decal

This design reproduces the Uniform flag of the International Code of Signals, a single square of red and white that ships and harbours have read for generations.

Visual Elements & Composition

The artwork is a flat, two-by-two checkerboard. Four equal squares sit in alternating red and white, so red and white each fill half the field. Nothing else is added: no lettering, no border, no numerals. The grid is rigid and symmetrical, and every square carries the same weight, which gives the image its immediate, graphic clarity. The checkerboard is the whole composition, and the die-cut sticker follows its square outline exactly.

Meaning & Symbolism

In the International Code of Signals, the Uniform flag is one letter of the alphabet used to pass messages between vessels by flag and by flag hoist. Its meaning is a warning: you are running into danger. The system was standardised internationally in the 1930s, building on nineteenth-century signal codes, and it remains in use at sea. The red and white checkerboard works as a signal because its pattern is instantly distinct at a distance, which is exactly what a flag at the masthead needs to do.

On the Holographic Die-Cut Sticker

A signal flag is a single bold shape read at a glance, and this sticker keeps that quality. Because the die-cut follows the square of the checkerboard, the artwork reads as one object rather than a rectangle with a picture in it. The holographic finish shifts the red and white as the sticker moves under light, adding a second layer of motion to a design built from strict geometry. For anyone who knows the flag, it works as a compact nod to the sea; for anyone who doesn't, it stands as a clean, graphic square.
