Color names in the current language in LaTeX

Question

Let's say we wish to verbalize the colors used in a document in the current language:

\documentclass[USenglish,ngerman]{article}
\pagestyle{empty}
\usepackage{babel}
\usepackage[x11names]{xcolor}
\usepackage{etoolbox}
\newcommand{\actionColor}{blue}
\newcommand{\actionColorGerman}{blau}
\begin{document}
Die Aktionen werden \ifdefempty{\actionColorGerman}{in Textfarbe}{\actionColorGerman} gesetzt.
\end{document}

yields

Die Aktionen werden blau gesetzt.

(Which means that the actions (whatever an action might mean in my text) are typeset blue.)

The current code is bad because \actionColor and \actionColorGerman are not tied together by a command. For example, if you change/remove one (say, blue), you may forget to change/remove the other (here, blau). Moreover, if you have a dozen of different semantic color macros \doodahXYZColor evaluating to blue and another dozen \gimmickXYZColor evaluating to red, you'd have to add a dozen of translations \doodahXYZColorGerman evaluating to blau and another dozen of translations \gimmickXYZColorGerman evaluating to rot. This is useless duplication.

Has some package already done the exercise of automatically translating the color names? I don't wish to reinvent the bicycle. Ideally, I'd like to have a macro

\colorInCurrentLanguage{…}

that takes an argument (in our MWE, \actionColor) and returns its translation in the current document language (in our MWE, blau).

For my current purposes, translations into German would do.
