## Overview

ShadeOfColor is a command-line utility that encodes arbitrary file bytes into PNG pixels and restores them later. The principal workflow starts with a user-supplied command, passes through argument dispatch, and invokes the conversion implementation; that implementation handles both pixel encoding and decoding, including embedded filename/size metadata and SHA1 verification. The README documents the two-way conversion and integrity check. Source excerpts show the calls and ImageSharp usage; filesystem interactions are visible in the conversion code.

Main entry points: [`ShadeOfColor2/FileToImage.cs`](https://github.com/archistico/shadeofcolor2/blob/main/ShadeOfColor2/FileToImage.cs) (File-image codec), [`ShadeOfColor2/Program.cs`](https://github.com/archistico/shadeofcolor2/blob/main/ShadeOfColor2/Program.cs) (Command dispatcher)
