There are multiple standards for this. - RAL – https://en.wikipedia.org/wiki/RAL_colour_standard https://en.wikipedia.org/wiki/RAL_colour_standard - Pantone – https://en.wikipedia.org/wiki/Pantone https://en.wikipedia.org/wiki/Pantone - some others, often with military roots (FS595, British Standard, …) Pantone has different charts for paper/textile prints etc. RAL is mostly used for paint. It's common to have RAL codes on spray cans or wall paint buckets here in Europe. There are tools to approximately convert RGB (and HSL and others) to these colors, eg. http://rgb.to/ http://rgb.to/. But since the color models and intended use are different, there are some colors with no equivalent. Pantone even provides RGB/CMYK mappings for applicable colors in their sample books: https://www.pantone.com/images/pages/19890/Pantone-Extended-Gamut-Guide-Proces-Colors.jpg https://www.pantone.com/images/pages/19890/Pantone-Extended-... There are also palletes for graphics software like Adobe Illustrator. But some colors look weird on the RGB display obviously.
