    }
  ],
  "dependencies": {
    "jp.keijiro.pugrad": "1.0.0",
...

How To Use

To cerate a colormap, select Assets -> Create -> Pugrad. It creates a .pugrad file that generates a Texture2D asset procedurally.

You can change the resolution of the texture on the inspector. You can also change the lightness of the gradient when using the HSLuv colormap.
