You guys are such squares. Remember when they replaced the google logo? It was some serif thing, they smoothed it out and made it look more modern. It felt terrible at the time, but nowadays when I see the old logo, I have to laugh at how silly it looks. I can't help but feel that the entire reaction to this change is born of familiarity. The author practically admits as much when he recalls hating a change to the gmail logo, only to have it grow on him. The new logos are kind of cute, honestly. Here's to the new!
i am usually the last to complain about these kind of redesigns, but when my mail notification icon changes from a universally standard envelop to an awkwardly-styled M, i think it's fair to say something is off.
There exists monochrome icons. I don't think all the icons having the same color makes it all that much harder to distinguish them. More likely, you aren't used to the new icons, and will have to wait a couple days to adapt. Not the best thing in the world, but c'est la vie.
