Here is an infographic featuring all the shades of violet (Hue 270).
P.S. I've highlighted all the colors you can use in commands to Google Assistant for changing light colors in your smart home!
Credit to http://veli.ee/colorpedia/ for the color names and http://colorizer.org/ for the conversion tool I used. I also like http://www.colorzilla.com/ for a browser plugin. You can use it to hover over the infographic get more details on the colors!
