9/12/2026 - THIS PAGE RELATES TO THE ORIGINAL 2015 BUILD MECHANICS. A new, more efficient build system was adopted in 2021.
Unless you are an advanced user, this reference is irrelevant today. To build on a tile now, use the Etheria Builder.
Color Reference
Each block in Etheria stores its color as a single signed number. This is the full palette — the number shown on each swatch is the value to pass when placing or editing a block (see How To Play). Every value is printed in both white and black so it stays legible on its own background.
