Here are some vector shapes that you can import straight into Krita and edit them however you want, including modifying colors and outlines:
Click here to download. The shapes will be ready to use as soon as you unzip the folder. To learn how to import and edit shapes in Krita, watch this video tutorial:
If needed, there is more information in this Krita Artists forum thread.
I’ve repacked your collection of .svg files into a vector library that can be Imported into krita as a vector library appearing in the Symbol Libraries docker.
I’ve called it Basic-Forms-A in case you make Basic-Forms-B in the future 
I’ve changed the fill to grey so that they are displayed better in the Symbol Libraries docker.
It can be downloaded from here:
Guerreiro64-Basic-Forms-A.svg
Note that any vector symbol, when dragged out of the docker onto the canvas, will have a level of grouping applied to it.
So you have to immediately do right-click → Ungroup on it to make it possible to change the fill and stroke.
This is a minor inconvenience and that applied grouping is needed to avoid breakup while moving and scaling etc of some types of dragged out symbols
Oh yes, thanks for doing this, Ahab. Honestly, I didn’t even know there were vector libraries in Krita. 
I just didn’t like the fact that I had to ungroup: I did it this way precisely to avoid this work…
I’ll keep the old link, so each one chooses how they prefer to use it. Tip: if you want to keep the old way and need to import a lot of vectors, it’s more practical to create a shortcut for the “Import Layer” command. In my case I assigned the shortcut: Alt+8.
Yes, I intended to create more vectors to include in the package… but I don’t know, exactly, which one you use the most in the arts. Maybe if you create a poll it will help to know.
