Note:

This question is similar to \textcolor{}{} behaves differently within a \node. The difference here is that

  • The problem occurs inside an \href (within a \node) and
  • The workaround hack solution I posted there does not work here?

Thus, I suspect that the problem is related but not identical. Would be nice to have a single solution that works for both cases.

I would expect that using the \MyText (containing an \href) macro defined as 

\newcommand*{\MyText}{%
    before \href{https://tex.stackexchange.com}{\textcolor{red}{{TeX.SE}}} after%
}

should always yield the same color for the text "before" and "after". But it appears that when I use it within a \node (third line), it results in different colors:

enter image description here

It seems as if the \textcolor{red}{TeX.SE} restores the color to black at the end if it is used within a \node.

Question: How do I get \textcolor{}{} within a \node to yield the same results as it does outside of a \node.

Notes:

  • Using \textcolor{}{} outside of the \href does allow the hack solution to work, but, then this won't override colorlinks=true (in case it is used)

Here is an ugly workaround that works both here and in the partner question: set the text color first just with green, say, and then set the other colors afterwards with draw=blue, fill=yellow, say. I am aware that this is not a real solution, just a workaround, but this seems to work. Moreover, the business is rather delicate, i.e. a real solution may break other codes that worked fine so far.

    Yeah, with all the issues I have had with this I am leaning towards going down this path and dealing separately with any issues regarding the order of the \tikz options. – Peter Grill Aug 27 '18 at 18:54

    @PeterGrill I fully agree it is ugly. And I am not suggesting that you go that path or even accept that answer, it is just meant for others that may have the same problem and need a quick workaround. (You could of course define a tikz style that does the ordering for you.) –  Aug 27 '18 at 18:58

    Agreed. \tikstyle is the way to go, but since my styles are often built up over layers, I need to be careful about the order. I suspect it will work just fine with perhaps a few issues that can be tweaked. – Peter Grill Aug 27 '18 at 19:16

    Oppsss. I meant \tikzset... Thanks for correcting that. – Peter Grill Aug 28 '18 at 03:36
