Concrete Tints 2.1 (fork)

Unofficial Factorio 2.1 compatibility fork of Concrete Tints by Adrien “Larandar” DUDOUIT-EXPOSITO, based on upstream 2.0.1. Maintained by justmebeky.

Makes the 11 built-in colored refined concretes craftable: red, orange, yellow, acid (lime), green, cyan, blue, purple, pink, brown and black. Each recipe converts 10 regular refined concrete into 10 colored tiles in 0.5 seconds. Recipes unlock with Concrete and work in assembling machines or hand crafting.

Existing saves and blueprints

Item, tile and recipe names stay the same. Disable the original Concrete Tints and enable this fork in the same mod change. Back up the save first, load using the current mod list, and save once with the fork enabled. Do not load and save in between with neither color provider enabled. The newly saved mod list can then find this published fork through normal Mod Portal synchronization.

Foundations is optional. Its existing color-layer settings and integration are preserved when it is installed. The original Concrete-Tints mod and this fork cannot be enabled together.

Validation

Tested in Factorio 2.1.24 in a fresh game without Foundations, and by switching an existing save from the original provider with Foundations 2.26.0. All eleven placed colors, landfill underlays, inventory stacks, assembler recipes and outputs, research state, and Foundations tile layers were preserved.
