# Welcome to LIMINAL

> Learn to use LIMINAL's beta tattoo workflows: technical sheets, Color Engine, Piel Viva photo tracking, and FISIO placement review.

LIMINAL brings four tools into a tattoo artist's workflow: technical sheet generation, Color Engine, Piel Viva, and FISIO. This guide covers the features currently implemented in the beta and explains their boundaries.

> [!NOTE]
>
> Automatic observations are working references, not final professional decisions. Review the results against the actual session.

## How the tools connect

A **session** holds the client, design, body area, and work details. Generate a **technical sheet** from a reviewed session. Color Engine records colour planning decisions. Piel Viva organises photographic observations. FISIO helps you review the placement visually on a 3D model.

## Before you begin

* Select the correct session when switching between tools.
* Check any automatic interpretation before acting on it.
* Use client photography only with the appropriate permission and privacy safeguards.
