Pugrad

Pugrad is a color gradient generator for Unity that provides a set of widely used, perceptually uniform colormaps.

Currently, Pugrad includes the following colormaps:

• Viridis, Plasma, Magma, and Inferno from the Matplotlib colormaps
• Turbo
• HSLuv (repeatable)

Installation

The Pugrad package (jp.keijiro.pugrad) can be installed via the "Keijiro" scoped registry using Package Manager. To add the registry to your project, please follow these instructions.

How To Use

To create a colormap, select Assets > Create > Pugrad. This creates a .pugrad file that generates a Texture2D asset procedurally.

You can change the texture resolution in the Inspector. When you use the HSLuv colormap, you can also adjust the gradient lightness.
