Achromatic: All Level Solutions Guide

This guide contains solutions to all 60 main and 10 bonus Achromatic levels.

The solutions in this guide are not the only solutions, nor are they necessarily the best or most efficient solutions.
Before each solution is the final colour that the level will end with.
In some cases, there is more than one possible final colour. In these cases, I have indicated the colour that the solution in this guide ends with.
Each step is included as a separate image in separate spoiler tags. In this way, it is possible to see only as many steps as necessary to provide a nudge in the right direction without completely spoiling the solution.
If you notice a mistake, if you find a better solution (less moves), or if you have any other positive or negative feedback, please feel free to send it. My hope is that this guide is as useful as possible to as many people as possible.
