MusicXML color attribute for chord tags not imported

Hi,

I'm working on a project around music analysis and I would need to color harmony tags in a musicxml file as the result of this analysis.
However, when trying to visualize the result of the analysis, I noticed that musescore does not deal with the color attribute for a certrain number of tags (and notably the harmony tag).

I understood from https://musescore.org/en/node/297906 that it is not an "high priority" feature, then I was wondering if I could give a try at implementing it. I never tried to collaborate to musescore or any open source project, so before I dive in and probably spend hours on it, I'll like to know if it is useful and if my pull request would be accepted if the coding is done properly?
