Hi List,
Talking about palettes is always difficult - at the end, it's a
question of taste. Nonetheless, we need a palette which is by default
installed with the office. You all know the current one (for years
;-)) which I think is far from optimal. Thus, I analyzed the current
one and want to share my findings. From that, I want to propose a
change for our next release. Also probably not optimal, but optimal in
this field depends on the user's eye and cannot be met by a single
palette anyways.
Talking about palettes is also difficult since you need to 'see'
something - pictures say more than words. To make that easier, I have
prepared some data. Please look at
A Impress document containing two slides
(http://people.apache.org/~alg/Palette/palette.odp)
The two slides as png's for convenience
(http://people.apache.org/~alg/Palette/palette.png,
http://people.apache.org/~alg/Palette/palette2.png)
The following thext refers to figures there, so please take a look to
see what the text is about (...if you want to continue reading ;-))
The current (old?) AOO Palette, It's made up of five groups (from my
perspective):
(a) The 16 VGA colors: These come originally from the times where only
16 colors were possible and are in hex color notation exactly all
eight combinations of red/green/blue on or off, plus these in half
intensity. It *had* technical reasons, but these colors do not have
any special meaning for the user today (well, for the programmer).
Anyways, they are a result of old technical limitations. I think they
are ugly and lead to ugly results when using them directly (but that's
my impression).
(b) The 'Main' Colors: 56 colors which try to build up to eight
gradient-stepped ranges, e.g. orange. These ranges are *not*
equidistantly spread, but somewhat wild/random (see e.g. the reds). I
do not know where they historically come from, but I guess they were
done by a deveoper at these days. There are some nice colors among
them, but not too many. I always search for useful colors there
(c) The Pale colors: These seem to be younger than the others, may
have to do historically with the StarOffice 5.2 color theme, but I'm
not sure. Not too bad, not too good a selection. A group of seven
colors which form a nice kind of 'schema' and make your presentation
look 'acceptable' when using them together.
(d) The Chart colors: 12 colors used in the new chart module written
some years ago. AFAIK these were added at that time especially to
support the user having colors at hand corresponding to the default
chart colors. Nice. Useful.
(e) 'Nice' Colors: A sub-group from (b). One is fix, it's the
mentioned 'Blue 9' which is currently the default color for objects
and has to be in the palette. I personally like (and often use) 'Blue
Gray'. These are a question of taste, I would reccomend the named
ones, but we need to collect 'your' favorites here. Keep in mind to
keep this number low (probably 4-5) and do not forget that the color
you like were not choosen freely, but *because* you were limited to
the offered ones, so it might be a compromize you are just used to.
Quite a mix. I compared it with Syphony's palette and there completely
new colors are used. One interesting aspect are the white/gray/black
ones: In our current palette these are divided between (a) (black,
white and two grays) and (b) (the rest, gray 80% .. gray 20%). This is
of course because the first four grays are technically in the old VGA
palette. I more than once were mad about finding the correct gray in
our palette, because of the bad positioning in it. Symphony has all
needed grays in one draw as first entries in the palette (what I would
expect nowadays).
Thus, I propose:
- Basically use Symphony palette
- Preserve some nice olors from our old palette, but not more than 4
or 5. The default color needs to be preserved (blue 9). I propose to
only keep 'Blue Gray', but let's see which other colors are favorites
here...
- Add the Pale colors
- Add the Chart colors
The result is 'hand crafted' in the docs linked above, please have a
look :-)
Another aspect of the new palette is that it copies from Symphony the
use of '12-er groups' which look nice when you order the palette in a
way that 12 colors are in a row, please see the picture. This could be
a part of our sidepane in progress.
One more hint: This palette offers defaults to the user after AOO is
newly installed, not more (and not less). It can be changed by the
user anytime. Colors can be added/deleted by the user. This has no
technical limitations in the sense that changing the palette may
influence existing ODF's or other written files. E.g. the chart colors
are there to not have to look for them, but can be added/removed by
the user anytime (they are *not* the source for the chart to use them).
Lot of text for some colors. So, tell me what you think about this
proposed new palette!
Sincerely,
Armin
