Colorify contains several shaders and helper scripts that let you easily recolor your assets without any additional textures. Includes Unity 5 standard PBS shader variants.

Use it to:
-Enable partial recoloring of existing assets - majority of Asset Store models don't have partial recoloring option. With Colorify, you can easily change color of the parts you need without touching anything else. (All example models are free downloads from asset store and contain only one diffuse texture and material without any built-in way of partial recoloring).

-Dynamically change color schemes of your objects (team colors, armor & weapon customization, character appearance etc.).

-Real-time preview of possible color schemes right inside your game-play, before preparing designated assets.

-Play with your colors and ranges procedurally to achieve some interesting effects (real-time spoiling fruits with spoiled areas growing gradually, "infection" effects on skin, smooth continuous color-swapping in real-time etc.)

- Alternatively, bake recolored textures into image files from editor or into RenderTextures at runtime, and use them in any material, without depending on Colorify shaders.

-Both real-time calculations and pre-generated masks support.

-Automatic in-editor mask baking.

Package includes:
-68 shaders total: Standard PBS, bumped, specular, transparent, cutout, unlit, dissolve versions. Every shader comes in 1 and 2 color, normal and mobile,real-time and pre-generated versions. For full list of shaders see file listing.
-Complete support for physically-based shaders, including options for changing specular colors and smoothness of recolored areas.
-Unlit versions designed specifically for sprite rendering.
-Mobile versions of shaders supporting shader model 2.0. Masked shader versions work on mobile devices without limitations.
-Toon outline shaders
-Maskless Dissolve shaders, using color ranges as dissolve masks.
-Examples for both normal and mobile versions.
-Playmaker support.

Colorify uses rgb distance and hue filtering to recolor parts you designate without touching everything else.
