5 In the current state of the .tex files shipped with the `fontawesome` package, the following should work for about everything, except the two special cases defined at the end of `fontawesome.sty`, namely `\faHourglass` and `\faBattery` commands that take an optional argument. For these, you can use simple, existing macros like `\faHourglassHalf` and `\faBatteryThreeQuarters`, or define your own commands using plain TeX syntax—hence no optional argument support without going to some lengths.

6 [samcarter's solution](https://topanswers.xyz/tex?q=7794#a7505) is quite fine. The purpose of this answer is to help you understand why your method didn't work. There are two problems:

4 The problem seems to arise from infinite recursion due to the `every path` style drawing paths which cause the `every path` style to be executed, which draws more paths, etc.

5 I think that the patch is not complete, for instance `\colorlet` also leads to an error. So I am wondering if defining your own fill may be an option.

4 @marmots great answer made me realize that I was totally barking up the wrong tree. Instead of trying to hack `xcolor`, one can tackle the problem from the `tikz` side.

3 Coming back to the original idea to hack xcolor. There is actually a package which already does something similar: The [coloring package](https://ctan.org/pkg/coloring) uses some hacks to define missing colours based the name of the colour for rgb, hsb or grey colours.

5 The following defines two functions `ymincalc` and `ymaxcalc` which implement this logic (using a common auxiliary macro and a bit of `pgfmath`).
