# Holo

> Dark surfaces, cyan-blue accents, thin lines, and the first attempt to give Android a coherent visual identity — before Material Design arrived.

## Where it came from

Holo was introduced with Android 4.0 Ice Cream Sandwich in 2011 as Google's first serious attempt at a unified Android design language. The design team built both light and dark variants; the dark one, with its deep charcoal surfaces and vivid cyan-blue accents, became iconic. It gave Android an identity distinct from iOS and established the base that Material Design later replaced in 2014.

## How to spot it

- Dark charcoal or near-black base surfaces
- Vivid cyan-blue ("Holo blue") accent colour
- Thin hairline dividers and sparse decoration
- Roboto typeface, introduced alongside Holo

## Strengths

- Dark surface reduces battery use on OLED (relevant then and now)
- Teal on dark has strong contrast and character
- Clean and consistent — clear improvement over earlier Android

## Weaknesses

- Replaced by Material Design — now obsolete on Android
- Dark-only variant can feel cold and dated
- Very specific to a single two-year era

## In the wild

- Android 4.0–4.4 system apps — Settings, Dialler, Messaging
- Gmail and Google Maps, 2012 era
- AOSP (Android Open Source Project) default apps

## Use it when

Android developer nostalgia projects, or apps leaning into the early-Android aesthetic.
