--- Comment #3 from V Stuart Foote <vsfoote at libreoffice.org> ---
This was by design to minimally impact the QA build testing.

For bug 114719 the standard pallet "Light Blue 2" tint and "Dark Blue 1" shade
were assigned [1] colors slightly off from the trilinear tensor calculated
value to retain standard fill (COL_DEFAULT_SHAPE_FILLING) and stroke
(COL_DEFAULT_SHAPE_STROKE) called out by xdef.hxx used extensively in test
files used by the existing QA tests.

At the time, it was decided that the shift of these tints/shades in the
generated standard pallet was more efficient than reworking the QA tests and
sample files, as the xdef.hxx defined colors had to appear on the pallet. 

It is feasible to replace all the impacted QA test files and scripts, but still
a lot of effort.

IMHO probably not worth the dev effort, but for a devotee to color theory it
might be appealing to tackle the changes.

Otherwise => WF

where these colors for Standard RYB pallet are defined: 
 <draw:color draw:name="Light Blue 2" draw:color="#729fcf"/> <!-- #85a4c5
actually but hard coded COL_DEFAULT_SHAPE_FILLING in xdef.hxx -->

<draw:color draw:name="Dark Blue 1" draw:color="#3465a4"/> <!-- #2e5d8c
actually but hard coded COL_DEFAULT_SHAPE_STROKE in xdef.hxx -->
