Currently both Spanish Language and Earth Science have a favicon that is almost the same (see Meta.SE Favicon of Earth Science and Spanish are too similar (exactly the same in HNQ list) and Earth Science vs. Spanish Language favicons: now with 0% lowercasing!).
While we are in Beta, we are supposedly not allowed to have our own style of icons. However, it is clear that the current situation makes both sites difficult to distinguish.
Prompted by CM Catija's comment:
If these sites want different icons that are still Unicode, that discussion needs to happen on their respective sites. It's not for MSE to decide if this should be changed and, if so, to what. I recognize that this question was originally asked on a child meta and that it was migrated here because it was about two sites. But the question isn't "should these be more different" the question is "do we want something else?" – Catija♦ Mar 20 at 18:51
I ask here: do we want a different icon? If so, which one?
