Indigo white logotype with exclamation-mark I on flat blue

Summary

The Indigo logotype set in white on an edge-to-edge saturated blue field, with the capital I split into a tall bar and a detached square so it doubles as an exclamation mark.

Visual description

A single flat blue rectangle fills the frame with no gradient, texture, or shadow. The word "Indigo" sits roughly centered in white, occupying a little over half the width and set slightly above the vertical middle. The first character is a straight vertical bar with a narrow gap near the bottom and a separate square block beneath it, so it reads simultaneously as a capital I and as an exclamation mark. The remaining letters are a heavy grotesque with a tall x-height, tight spacing, and flat horizontal terminals: an n and d with squared shoulders, a dotted i whose square dot aligns with the block below the opening bar, a double-storey-free g with a wide bowl and a small flag curling off its upper right, and a nearly circular o. There is no tagline, symbol, rule, or secondary text anywhere in the frame.

Key takeaway

The whole identity idea lives in one letter: cutting a gap into the I turns a neutral initial into punctuation, so the brand name carries its own emphasis without any extra mark or exclamation added after the word. Restricting the frame to two flat colours and nothing else forces all attention onto that substitution.

Reuse notes

Reach for this when a single-word name has an I, l, or i that can absorb a punctuation or icon substitution, and the brand wants one memorable detail rather than a separate symbol. It only works at sizes where the gap in the bar stays visible, so check small favicon and app-icon crops before committing. The flat two-colour treatment makes it easy to invert, but the exclamation reading weakens on busy or photographic backgrounds where the detached square can be mistaken for a stray element.
