When you first decide to texture paint an object, you are given the option of adding a paint slot.


You then can choose the base color to start out with.


But what if you later decide that you want to change the base color you started with? Are you able to change it without losing the texture painting you've done? It's understandable if this isn't possible, but I can't even figure out how to delete the paint slot and start over. At least that should be possible! Anyone know the answer to this?

As far as I'm aware you can't change to base color later on. Basically it just creates a flat image with the base color that you're panting on. You can remove the material base slot by deleting the underlying image. This can be done by going to the image editor, holding shift and clicking on the unlink button. Once you save & re-open the file the image will be permanently deleted and the slot will be gone too. How to permanently delete image

You can change the base color.

Starting in Blender 2.8, the UV/Image Editor has been separated into two different Editors:

  • the UV Editor and
  • the Image Editor

Let's look at you what happens when when you're in Texture Paint Mode and you make a new Texture Slot, and how to change the color later on.

All hyperlinks below link to the Blender v2.83 Documentation.

Setup :

In the following example, I resized the default cube, and sculpted a crude rock.
No materials nor textures have been applied. No other changes yet.

1st step, Add a Base Color to the Texture Slot :

In the following picture, I have four Editors open in four Areas1,

  1. Image Editor
  2. 3D Viewport in Texture Paint mode
  3. Outliner in the upper right
  4. and the Properties Editor

1--Basic Mesh, No Texture Yet

Look at the Properties Editor.

Under the Texture Slots Panel, it says "No Textures" by default. Click the [+] button and click "Base Color" in the Context Menu. You can click the field for "Color" and select the base color for the Texture Paint Slot from the Color Wheel (shown in this next image).

2--Create "Texture Slot" with a Base Color

Not shown in picture: I then renamed the Texture Paint Slot "Base Color for TexturePaintSlot", to make it apparent when we find it later.

2nd step, Find where this color data was saved :

We can now see that the mesh is displayed with a different color in the 3D Viewport's Texture Paint mode. We see this same color in the preview square to the left of our newly created Texture Slot, but it is nowhere else in the entire Properties Editor.

So where is this information stored?

3--Texture Slot's color is displayed in 3D Viewport

If you don't have one already, open an Outliner Editor.

4--Select an Outliner Editor

Once the Outliner is open, click the "Display Mode" button in the Editor's Header (next to the "Editor Type" Button) and select either Blender File or Data API. Each are shown in the following image.

Here we see the name we typed ("Base Color for TexturePaintSlot")
nested under Images.

The data we just created for the Texture Slot is an Image.

5--Outliner showing the datatype for our Texture Paint Slot

3rd step, Change the Color :

Open the Image Editor and click the dropdown for "Browse Image to be linked" and select the name of the Texture Paint Slot created in the 1st step above.

Note, this means you are "linking" the image into the Image Editor. Similar to how if you change Scenes using the Topbar2, the tooltip displays "Browse Scene to be linked". If you'd like to know more, read about Data-Block Menus3.

6--Image Editor before Color Change

To change the color of our Texture Paint Slot image data:

  1. Change the Image Editor's mode to Paint.
  2. Select the Fill tool in the Toolbar.
  3. Change the color for the tool.
  4. Click on the image.

7--Change Mode for Image Editor 8--Finally change the color.

Concluding Remarks :

It would be nice if we were able to change the color by clicking that little preview square in the Texture Slots Panel, especially if you change your mind and just wanted to make a small tweak.

But for now this is a fairly straightforward way to change the base color (once you understand how the datatype works).

If you'd like to non-destructively change the color, simply go back to the 1st step above, add a new Texture Paint Slot, and select it in that Texture Slots panel. Then follow the rest of the steps and modify your new slot instead.

I figured out how to at least change the base color, but by losing all prior painting work. If you go to the UV image editor, go to the footer and click Brush. From the drop-down check Unified Color.


Then go to the tools panel and set your texture painting tool to fill. Now you can change your color to whatever you want and then simply click your model. It will set the model to that solid color. Just make sure you have your tool at strength of 1.
