What you need is palettes with metallic colours and a software that can store them as spot colours, 
because otherwise you won't be able to export any file that a digital print shop can use. 
LibreOffice is the wrong software for this purpose. You should also be aware of the fact that 
metallic and neon colours depend on the printing machines available in a print shop. For instance, 
a shop using Roland equipment will only be able to reproduce Roland metallics etc.

You won't find any metallics or neons in the OCSC for the reasons I mentioned.
What I am asking for as "metallic colors" are those that are colors closest to the "metals". Below is a list of metal colors that I know of. I would love to find more, or better looking, HEX code for all the "standard" metal colors. A single color that will make background, "highlight", or font color, look gold, silver, copper, bronze, etc.

<draw:color draw:name="Cool Copper" draw:color="#d98719"/>
<draw:color draw:name="Copper" draw:color="#b87333"/>
<draw:color draw:name="Copper-Red" draw:color="#cb6d51"/>
<draw:color draw:name="Copper-Penny" draw:color="#ad6f69"/>
<draw:color draw:name="Copper-Rose" draw:color="#996666"/>
<draw:color draw:name="Gold" draw:color="#cd7f32"/>
<draw:color draw:name="Old Gold" draw:color="#cfb53b"/>
<draw:color draw:name="Brass" draw:color="#b5a642"/>
<draw:color draw:name="Bronze" draw:color="#8c7853"/>
<draw:color draw:name="Bronze II" draw:color="#a67d3d"/>
<draw:color draw:name="Silver"draw:color="#e6e8fa"/>

I am not looking for printing out a sign where there are places that actually look like being made of metal. If I need an "object" in a document, I go and use a package that can use scanned in metal images. Inkscape or GIMP would be my first package for this. I have done this many times, but it is a chore creating all the "metal looking" text, background, etc., images and then use them in LO. Having a single color that looks close to the various shades of the metals is what I am looking for.

Finding good metallic colors
are always - for me - a pain for both LibreOffice and GIMP. I know the
.soc "standard" for LO, but not what GIMP uses.
GIMP, Inkscape, MyPaint etc. are really behind when it comes to palette files, because a SOC file 
doesn't need anything but RGB values (and licensing information). However, the other programmes I 
mentioned are more ambitious than LibreOffice, but the GPL format is just plain RGB values. No CMYK 
colours, no spot colours, which is a shame.
Yes, I would love some internal way to choose from a large predefined color palette like we have in LO. Right now, I have to take a screen shot of the LO color picking dialog that has the color[s] that I want, then use that image withing GIMP to pick the needed color from that image. I have done that many times and never like it.

IF you know of some other .deb package that does this better than GIMP or Inkscape, let me know. I run Ubuntu 16.04LTS most time. My Windows default package is Paint Shop Pro [a version from 2014 or 2015]. For some reason GIMP seems not to run properly right now on Windows 10 [Win7 works though].

If you need metallic colours for printing with a Roland machine, I could create a SOC file and send 
it to you privately, but I doubt that it would be of any help. Exporting files for this kind of 
specialised printer is  simply beyond the scope of LibreOffice.

I do not have access to any "professional" printers. When I need better prints or larger formats than 13x19 inches, I go to local print shops. They "prefer" PDF file formated documents. I have never needed to make my document into a separate file per color, which are needed for high volume offset printing.
