Excel Color Palette problem ...
Didn't he say they wrote a Biff8 file - just like Excel/any workbook file,
it would include information on the formatting of the cells.

Something went totally wrong with my transcription of the second colour in
your list -
colorindex 18/54 colour-value 6697881
is in fact
colorindex 2, colour-value 16777215 (#FFFFFF - white)
Your colours are comprise the original "16" video colours
Curiosity - how do your 3rd party components colour format Excel cells
without using COM or OLE.

10x Peter for quick responce.
I am using a 3rd party components, which seems to not treat the color
problem quite well. They do not use COM or OLE for creating the Excel
file,
insted they created the file on the fly in binary format (i think it's
called
biff8).
The problem was that almost non of the color matched. I searched the
forum
about similar problems and replaced thier color palette with the one
from
the
link above.
It seems to handle the first 8 colors, not the rest. But there might be
an
issue with their code, I will have to recheck it again.
But since you confirm the color palette is OK, I will put more efforts
on
debuggin the code.
10x again!
How did you define and/or apply your custom colours.
All the colours in your list are colours that exist in the default
Excel
palette, assigned to the following colorindex's (in same order as your
list)
1 18/54 3 4 5 6 7 8
9 10 11 12 13 14 15 16
(18 & 54 colorindex's have same colours in a default palette)
the equivalent "long" colour values are
0, 6697881, 255, 65280, 16711680, 65535, 16711935, 16776960
128, 32768, 8388608, 32896, 8388736, 8421376, 12632256, 8421504
If you have either applied these colorindex's or colour's as formats
your
colours should print correctly (subject your printer)
However if you have applied some other RGB colours that do not exist
in
the
default palette, then colours will map to what Excel calculates is the
closest match to one of the default colours, then apply the colorindex
holding that colour.
You can customize some palette colours as required, then apply either
the
relevant colorindex or the RGB value.

Hi to all,
I have a very strange problems with colors.
I have a program that does some database reports and brings those
report
to
the user. Then the user can print and export to excel /using 3rd
party
components/. Everything is going ok, except when using custom colors
for
the
grid background.
Then some odd colors are used when the report is opened with Excel,
not
the
colors I defined.
I searched the newsgroups and found out that there is a
DefaultColorPalete
thing.
Then I found:
http://www.mvps.org/dmcritchie/excel/colors.htm
I tested with this color list, it seems only the first 8 colors are
ok,
while the next 8 are not.
Here is the list I used (from the link above):
$000000,$FFFFFF ,$FF0000 ,$00FF00,$0000FF, $FFFF00,
$FF00FF,$00FFFF,
$800000,$008000,$000080,$808000,$800080,$008080,$C 0C0C0,$808080);
I used Excel97 and 2003 for testing - same strange results for both.
Any suggestion? Please!
