It's BackColor property did not work by default: Accorthing this (ToolStripSplitButton BackColor does not work), follow these two steps:

1) Set BackgroundImage to a valid image. It does not matter what. I use a 1 pixel x 1 pixel BMP as local resource.

2) Set BackgroundImageLayout to None. This is why it does not matter what image you use above.

Result:

That didn't have any effect in my case. The color of the dropdown didn't change. – Matt Aug 01 '23 at 09:06

You can use a custom renderer for the toolstrip, you can found a sample in this answer for a similar question.

**How?** Neither `ToolStripButton` nor `ToolStripSplitbutton` have a `Renderer` property. Only `MenuStrip` and `ToolStrip` have that. How would you assign the renderer mentioned in the link? – Matt Aug 01 '23 at 09:12
