A FEW ODDS AND ENDS ABOUT ARTISTS PAINTS
Often you will see the word "hue" in a color name, e.g. Cadmium Yellow Hue.  That signifies that the color contains a man-made substutute for the original (usually) metallic color.
 While these hues are normally lower in price than the traditional color, they are not necessarily inferior.  In some cases they have entirely replaced a traditional color, especially where that color was fugitive or of high toxicity.

Regardless of the medium, colors with identical names,  but from different makers,   will frequently differ slightly both in masstone and in tints.

And two notes about color that will do no good whatsoever to an artist, but which you may find interesting:

The color magenta was named after the Italian town Magenta, site of a French victory over Austria in 1858, the same year that the aniline dye which pro-duces the color was discovered.

Cobalt Blue derives its name from the German word for goblin.  It was so named because the German miners who extracted the ore from which it is produced believed that the mine was haunted by goblins.
