If that is what they are call them what they are not something else.

But at least they put a name there! Icons are [already] a terrible idea if there is enough space, they just fail to explain what they are but if you make them all the same color explaining or remembering how to navigate menu's to do something gets even worse.

Like click on: this > then this > then this > then this

Becomes: ? > ? > ? > foobar!

The color picker is one of the few that could have had a self explanatory icon. Its the easiest feature to find in nearly all other applications.
