Bug ID: 163535
Summary: Default color palette has (multiple) pairs of
overly-similar colors
Product: LibreOffice
Version: 24.8.2.1 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Chart
Assignee: [email protected]
Reporter: [email protected]
This is the default color palette for charts (or chart area fill color),
encoded in RGB:
0x004586 0xff420e 0xffd320 0x579d1c 0x7e0021 0x83caff 0x314004 0xaecf00
0x4b1f6f 0xff950e 0xc5000b 0x0084d
see also the soon-to-be-attached spreadsheet and chart.
Now:
* The blue and purple are relatively close together, for darker colors, and are
not easy enough to distinguish IMHO, epdeically when considering the legend,
* There are mostly "darker" colors, less lighter ones (e.g. orange and
faded-blue).
* Many "famous" colors are not used; which in itself is ok, but I suspect the
coverage of the space of possible colors is poor. Just adding, say, some shade
of pink could have been nice and would have been quite distinguishable from the
other colors (not to mention possiblitiess for replacing an existing color).
* They yellow and organge are a bit little too close to each other; and so are
the dark green and the dark reddish-mauve (0x579d1c), especially in the legend.
So, I suggest the default palette be tweaked for better "distinguishability".
PS - I know that different people's color perception is different. I'm not
diaganosed with any problem in this respect, but I still realize my complaints
may be somewhat subjective.
