I could have defined my own colors manually using the Color Picker, but "mixing" colors by specifying RGB or CMYK numbers is a cumbersome, hit-or-miss process. LibreOffice also lets users load predefined color libraries, but none of the ones I found suited me. Instead, by working with web-standard colors plus a little bit of awk scripting, I managed to create my own color list, providing well-organized colors, grouped in families, with as many color variations as I wanted.
The Impress and Draw components let you load a new color list and add colors to it, which is an option if you just need one or two new colors and know how to define them. (An aside: Any color changes you make in Impress or Draw become available for all LibreOffice components.) Open Impress or Draw, go to Format -> Area -> Colors, and you'll see the table of all available colors, with their RGB and CMYK equivalents, along with commands for editing the list:
