BL’s ‘Medium Brown’ is LEGO’s 217 Brown, introduced in 2004 and retired in 2007. I noticed that the head in that new Harry Potter set is far too similar to 217, which is why I’m beginning to question whether this new color is 217 but under a different ID, if this new color has already been scrapped and Brown is back, or if this is a new color for 2022. Guess all we can do is wait and see!
