Colour Sorting Strategy

Every shelf section in Clean The Library has a spine-colour signature — dark red for horror, purple for fantasy, blue for science. Learning that map is the single biggest jump in throughput a new player can make, because once the colours are in your head you can grab a fistful of books and route every one of them in seconds.

The full step-by-step version of this guide is coming soon. We are verifying the details against community runs and the official Clean The Library wiki before publishing the longer walkthrough, so the public version stays accurate.
