Including a filament that I haven't chosen

[oviano]

It’s probably some setting I’ve missed, but this unicorn came out with all these black stripes, but I haven’t selected that filament either for the main object colour or the support.

So where is the setting that is making it choose the black?

It’s likely painted. Click the model, then up here in the toolbar:

Yes, that was it. Thank you so much!
