Comment 9 for bug 1374870

Minor Inconsistencies (default guide color overriding custom guide color(s)) with extensions, and undoing extensions:

Steps to reproduce:
1) launch Inkscape (default prefs, new default document)
2) create two guides, change color of one of them to red
3) apply an extension (e.g. 'Extensions > Render > Gear > Gear...')
--> both guides are rendered in default guide color again (blue)
4) save file, revert (or close and reopen)
--> custom guide color is restored for the one guide changed to red

Steps to reproduce:
1) launch Inkscape (default prefs, new default document)
2) change default guide color in 'Document Properties > Guides' e.g. to green
3) create two guides, change color of one of them to red
4) apply an extension (e.g. 'Extensions > Render > Alphabet Soup'
--> guides are still ok
5) undo the extension (Ctrl+Z)
--> all guides revert to the default guide color as defined in 'Document Properties' (green)
6) save, revert (or close and reopen)
--> guides are again rendered as expected.
