Just in case anyone else finds this and is trying to do the same thing, I managed to achieve this (with the help of a kind chap over at SO) by applying a *MutationObserver *to the chart container and modifying the fill color of the rect as it's created.
http://codepen.io/awenborn/pen/jAjxjg http://stackoverflow.com/questions/38741949/google-visualization-charts-api-changing-highlight-color-of-explorer-function It's quite a crude solution and there's probably a better method out there in terms of performance and compatibility, but it works for my needs. <https://lh3.googleusercontent.com/-3BKNSIB0GIM/V79aDardXAI/AAAAAAAAFmc/E_HkCK7m3FAOwHET7f3r0DZMd_7GxlN5ACLcB/s1600/jbjkbjbjb.png> It'd still be nice if a future release of Google Charts could include an *explorer.color* parameter to achieve this and eliminate the overhead that my primitive hack requires!
