This is a follow up to Could we lighten up the Google+ icon a little? which I think was unfairly declined. On Stack Overflow, Super User and Server Fault the Google+ icon is less distracting because its saturation is more in sync with the surrounding icons. Compare the following of which the left is from TeX.SX and the right one is from Stack Overflow:
The Stack Overflow Google+ icon is clearly desaturated, less obtrusive and it fits better with the surrounding icons. In HTML notation the color of the Google+ icon at TeX.SX is something like ae503e and on Stack Overflow something like 8d4c45, so they are not only visually different.
Can the TeX.SX Google+ icon be desaturated so that its color is similar to the one on Stack Overflow? This would not only make the icon less disturbing on TeX.SX but it will also contribute to the consistency of design across the Stack Exchange network.

Of course, bounty reward icons are only ever placed on answers and Google+ icons are currently only placed on questions. Still, the Google+ icon may introduce unnecessary confusion. For example the following may be confusingly alike when only glancing:
