Nabla — the isometric color font

by Arthur Reinders Folmer & Just van Rossum

Nabla. Isometry, typeable

Isometry is once again cutting edge with Nabla, the isometric color font! Nabla showcases unprecedented possibilities and customization, allowing you to create bold and vibrant designs. Inspired by vintage computer games and using the isometric cube as a starting point, it goes beyond pixel-lettering, creating new lettershapes suitable for the technology of today.

And best of all, it’s open source and free to use!

Cutting edge technology

Designed by Arthur Reinders Folmer (Typearture) and engineered by Just van Rossum, Nabla is built using the new COLRv1 color-font format, allowing smooth gradients, sharp highlights and blended shadows to be captured inside a font-file. Internal palettes give the option for ready-made color swaps, while implementation on the web allows you to choose your own hues.

And Nabla is more than just a color font, as its variable axes allow highlights and extrusion depth to be changed, making it a typographic playground you can customize to your hearts content.
