Haha, that is a little rude, but I am going to assume you mean well.
While these two are technically different colors, it was easy enough to fool me (and likely others) for the first time as every single other bubble has a different icon and significantly different color, including the shield bubbles.
I think my main comment also might have come off the wrong way, I do like the game quite a bit. This is just a small suggestion that I disliked in my playthrough.
Interesting, I did not know about the color blindness thing, that is good to know.
As for the new colors, it looks a bit darker, not sure if that is just from a different background but overall it looks the same. I'm not proficient in color theory unfortunately so I cannot give much advice on that, but changing the icon should help make it look more unique. I think the idea of doing a cock icon is a pretty good idea and that might distinguish them from the hearts. Or you could maybe to lips, that might work too if you don't want to go the explicit route.
