Yes, gems and potions are a different color on the ground - I'm pretty sure that's documented in the patch notes.
What I meant was the actual gear on your character as you run around or on the selection screen. I didn't see any notes that they were going to bump the intensity of gear dyes, but it kind of seems like that's what happened. I will try to re-dye tonight and see if it reverts. As mentioned, the aqua doesn't look near as nice as the light blue from before.
