I bought the brighter green a few months ago, and a week ago, the greyer green one arrived. I was actually going to do a post asking which one would be better to keep for my skin tone because I thought they looked too similar to justify having two of them, (I’m trying to not buy any more clothes). However, as I was taking pictures, I realized that on camera, they look very similar, and I was trying different lightings and they just looked way too similar to be a coincidence. So I had a look at the codes and they are the exact same apart from one has 22 and the other one has 23, which I’m assuming are the years that they were manufactured. Just wanted to share because it’s quite interesting how the exact same color can look so different! I’m not sure if it was a manufacturing situation where one year they used a different dye or they changed something, or if this is just fading or the effects of laundry detergent, because I bought both secondhand.
