And I try to make animated stump with colored images. Though they appear greyscale

Does it have to be that way?

Edit: Krita 4.4.8 is ok with colored stamp.

For me it works correctly (but the preview is in grayscale like you show). Make sure brush mode is set to Color Image when you select the brush tip. Does that work for you or still in grayscale?

However I found that gimp image brush files (both gbr and gih) saves/exports and opens as grayscale in Krita 5. (File → Save/Save as…/Export)
.gih and .gbr files saved in Krita 4.4.8 opens as grayscale but appears correctly when used as brush stamp for me.

I reported the bug here: 442316 – Gimp image brush file (gih, gbr) with color saves and opens as grayscale

Hm. Yes. If I go to brush settings with newly created stump I can change it to color Image.

The confusing part is that in 4.4.8 you can see the thumbnail colored. In a new version it is grayed out.
So by the preview you assume that color information will be lost.
