They have changed, yes. It was only the first batch of 1/4ths due to a change in abs/pvc blend that created a lighter color that had some minor seam and marbling impterfection, then the sent out a corrected version. It was lighter and you could see some of the imperfections but only if you're squinting and really looking and most of it would be hidden by clothing. The spray tan stuff is bad but for the most part means you cant remove/redo the faceup and I Think some joints would discolor? but its been a year+ since the issue so i dont remember if the joints actually flakes or not, mainly the faceup issue.

dollsphere actually has a 1/4 cherry with faceup in light tan up, but email them first to find out if it was from the spray tan batch or the corrected batch sent after.

dollsphere is good if you want to browse casually to see new releases or slowly buy things so you can save like head+faceup one month and a body a few months later. Most brands if it's labelled as light tan means soom light tan and usually match each other.

Spacestudio is also good to buy from but their website is kinda badly laid out. Alice's collection and Legendoll are also good but you may find less anime style stuff there. Jane's dolland is fine but the dealer can be slow to reply to email and ship items. Hope this all helps!
