Yeah, @BambooGarden and I also came across the issue with the logo appearing black. It appears blue when I open it in a Web browser, but it appears black when I open it in any other image viewer.
However, I only have basic familiarity with image editing, so I don't really understand what the cause is. That SAFE Network logo mark from the MaidSafe Brand Assets page is the only source I am aware of for the proportionally correct version of the mark. But, based on the experiences a few of us have had with it now, it seems like it may have a color/transparency error of some sort? (Just a guess on my part.)
I worry that if we only replace "safeicon.png" in the repository, but leave the current "safeicon.svg" there, that someone else in the future might run the script again, using the disproportioned "safeicon.svg" currently there (not realizing that it is the older one with the errors), which will then overwrite the PNGs again.
I wish I could be more helpful, but it's mostly outside my area of knowledge. Hopefully others with more understanding will have some ideas.
