Why we like it

Color Randomizer earns its place in the blender_extensions library as a small, focused utility for randomly assigning colors to objects. What stands out is how direct it is: a single button press randomizes a color, and you keep pressing until you land on one you like. The prefix system that keeps each color unique, together with the multi-object support added in 1.3.0, makes it a tidy option for producing quick colour variety across a selection.

What is Color Randomizer?

Color Randomizer is a Blender add-on from ilumetric that randomly assigns colors to objects. It addresses the situation where adjacent objects end up with the same or very similar colors, helping produce a vibrant variety across a scene.

The add-on works from a single button press: it randomizes an object's color, and you can keep pressing the button to manually settle on the color you want. To keep each color distinct, it adds a prefix to object names, and that prefix can be removed once your work is complete. Version 1.3.0 added the ability to work with multiple objects simultaneously.

Color Randomizer runs inside Blender 4.2 LTS and newer, and version 1.3.0 introduced support for Blender 4.2. It requires no special permissions and is distributed under the GNU General Public License v3.0 or later. Source code and issue reporting are available on the developer's GitHub page.

Who is Color Randomizer best for?

Color Randomizer is best for blender users who want to quickly assign varied random colors to objects and avoid adjacent objects sharing the same or similar color.

How much does Color Randomizer cost?

Color Randomizer is completely free to download and use.

Frequently asked questions

Does Color Randomizer work with Blender 4.2?

Color Randomizer lists compatibility with Blender 4.2 LTS and newer, and version 1.3.0 specifically added support for Blender 4.2. If you're running a recent Blender release, the add-on should install and operate as intended. You can add it by dragging and dropping the extension into Blender, or by downloading it and installing from disk. For Blender versions below 4.2, compatibility isn't stated, so checking the developer's GitHub page is the safest way to confirm before installing on an older build.

Can Color Randomizer randomize multiple objects at once?

Color Randomizer added the ability to work with multiple objects simultaneously in version 1.3.0. With a single button press, the add-on randomizes an object's color, and you can keep pressing to manually select the color you prefer. It also adds a prefix to object names so each color remains unique, and this prefix can be removed once your work is complete. The add-on addresses adjacent objects ending up with the same or very similar colors, which helps produce a vibrant variety across a selection.

How does the name prefix in Color Randomizer work?

Color Randomizer adds a prefix to object names to ensure each color is unique. Once your work is complete, the add-on lets you easily remove this prefix, so your object names can return to their earlier state. The color randomization itself runs from a single button press, and pressing the button repeatedly lets you cycle through options until you find the color you want to keep. The prefix behaviour is part of how the add-on keeps assigned colors distinct across the objects you're working on.

Is Color Randomizer free to use?

Color Randomizer is listed here as free, and it's distributed under the GNU General Public License v3.0 or later. The extension requires no special permissions to run inside Blender. For the current licensing terms, source code, and any conditions attached to the GPL, the developer's GitHub page is the best place to check, and you can also report issues there. Since it's a small add-on distributed through Blender's extensions system, you can install it by drag and drop or from disk.
