As you can read athttp://www.haiku-inc.org/logo-design-details.htmlthere existing a white and a black Haiku logo.
The white one you can find as svg athttps://www.haiku-os.org/images/haiku_logo_white.svgBut there existing no black one athttps://www.haiku-os.org/images/haiku_logo_black.svg
The Wikipedia have two black logos.One of it is in png format
and the other one is the old logo in svg formatMore about old logo and new logo you can find athttps://www.haiku-os.org/blog/koki/2009-11-25_what_do_you_know_about_haiku_logo/
I have now taken the white svg logo and have changed all #ffffff to #000000http://svgur.com/i/1bs.svgIs the resulted one then the real Haiku black version or differs it in some points.Still missing a place, where you publishing Haiku logos for download.
The black logo is not just about the text color. The color of the leaves is also slightly different, and so are the shadows/glows.You can easily export an SVG from the original Wonderbrush files.
And where are the Wonderbrush files????
Here is Wonderbrush itselfhttp://yellowbites.com/wonderbrush.html
But the Haiku Logo files are nowhere publihsed.
There existing only an eps file of the old logohttp://www.seeklogo.com/files/H/Haiku_OS-vector-logo-A353B8D32F-seeklogo.com.zip
Sorry, I did not notice you were not pointing your links there already!The files are in Haiku git repository, in vqrious formats including Wonderbrush sources:http://cgit.haiku-os.org/haiku/tree/data/artwork
