You have been bitten by an Inkscape/Fritzing incompatibility (and there are a number of other problems.)
The color problem is that Fritzing is using the fill (green) in the fill attribute (circled in green on the right) Inkscape is using the style command value (black) circled in red on the right. The best cure (and what I did) is run the finished part through FritzingCheckPart.py which is available here:
among other things, it deletes inline parameters like the fill and moves the values in the style command to inline xml (because in some cases, Fritzing does not support style commands!) so both Inkscape and Fritzing are using the same parameters and thus what you see in Inkscape is what you see in Fritzing. Then I noticed the view box is too large because there is an unused path way to the side of the part, so I deleted that to reduce the size of the viewbox to only the part, as it should be.
Next the view box doesn’t start at 0 0 (which will cause grid offset issues in Fritzing) so in Inkscape do Edit->select all then Edit->resize page to selection to correct that.
As well the svg is missing the breadboard layerId (which will cause the part to not export as an image) so click Object->group to group the entire image and name the group breadboard. Next FritzingCheckPart.py warned that the drawing is dimensioned in px rather than inches which can (and does in this case!) cause scaling problems.
In this case this didn’t help, because the drawing is in a different dpi than my copy of Inkscape as we will see later but this is how the drawing should be dimensioned.
When I saved this breadboard svg, and made a part from it and loaded it in to Fritzing we see the scaling problem.
The top connector is a 6pin header dragged in the the sketch from core parts (circled in green) that is correctly aligned on the .1in boundaries. As we see the connector in the part (circled in red) is shorter indicating its scale is incorrect. To fix this I first selected connector1pin whose x coord is 0.219in then selected connector0pin whose x coord is 0.136in (and should be 0.119in to be on a 0.1in boundary.) That means the drawing needs to increase in scale by 120.4819277108434% to make the pins be on 0.1in boundaries. To do that set Inkscape like this:
lock height and width to scale together, change dimensions to percent (all are at present 100%) and enable scale stroke width when scaling (all circled in red above.) Now change the width to
120.4819277108434%
which rescales the drawing so the pins are on .1 in boundaries
connector0pin is now 0.164in in x
and connector1pin is now 0.264in in x as desired. However because of the rescale, the viewbox is now too small
so do Edit->select all, Edit->resize page to selection and then Object->group and rename the group to breadboard to create a correctly scaled svg with the layerId and save it as plain svg.
Now when I run the part through FritzingCheckPart and zip it to create
NRF24L01-BOv2.0-fixed.fzpz (64.3 KB)
the part is the correct scale in Fritzing (and the correct color!)
