Hi Toki,

Thanks for making sense :)

In the CIE-HLC palette colours are ordered by Hue - Lightness - Chroma in increments of 10, e.g., 
HLC 000-00-10, HLC 000-00-20 etc. After some experimentation we found that this model is the most 
user-friendly, compared to the more common LCH or HCL (not to mention LAB), because it's much 
easier to find a colour in the printed reference. Actually, it's much more efficient than any other 
colour reference I've worked with, including Pantone and HKS. So yes, it's *very* important for 
colours to be named, especially if you're working with a physical colour reference.

It would be even better if the ODF spec could be extended to be able to store named colours as an 

As to the number of palettes, I'd suggest a basic palette, e.g. 128 or 256 colours plus CIE-HLC. As 
for the rest, the suggestion of using extensions (plural) makes sense:

- one with all the palettes currently shipped with LO;

- another one with the Open Colour Systems Collection (more than 360; the number of colours per 
file varies between a handful for foils and more than 5000 for car finishes; CC licence);

- I can also create SOC files from the palettes currently shipped with Scribus, including various 
government standards (US, DE, NL, CA, UK; mostly Public Domain or similar);

- Finally, I could also create SOC versions of all colour palettes provided by the New Zealand 
colour vendor Resene. They are under a BSD-style licence, so the distribution would be OK.

Unfortunately, I've no experience in building OXT files, so I'd need some assistance or someone 
who'd do the building for me.

On a final note, I wonder why there is a file called "scribus.soc". These are not the colours of 
any of Scribus's "native" palettes but the old X11 colours, so the correct name would be "X11.soc".

Kind regards,

Go back to 2004, and there were complaints from some people that the
palettes for OOo didn't contain enough colours. Those complaints were
what prompted me to create the colour palette at

The second most common complaint I've received about that palette, is
that the colours are not named. The most common complaint is the obvious


The size of the palette is not an issue, _if_ the colours are
consistently ordered by hue ,chroma, and lightness. When colours are
randomly ordered, such as by RGB value, or alphabetically, the palette
becomes, at best, awkward to use.

Should we limit the number of palettes, 

Ship with one palette, but have additional palettes available for
installation as an extension. ZD_Color_Palettes.oxt being an existing,
albeit somewhat dysfunctional example.

have also a manageable size in terms of <50 colors (this is a very
arbitrary number), postulate elaborated color names?

Personally, I think that the minimum size should be 128 colours.

One might be able to get away with a 64 colour palette, if alternative
palettes are _easy_ for non-technical people to install.
Both ooespalette.1.1.oxt and ZD_Color_Palettes.oxt throw an error, when
attempting to install their *.soc files using the extension. For
non-techies, this is a fail.


One other item to be considered, is that switching palettes from within
LibO usually requires the program to be restarted.  (My normal practice
is to close LibO, copy the palette I want to standard.soc, then start LibO.)
