Modification How to save a tan BJD turned green ?

New If it's just the face or other isolated spot that doesn't get touched/ moved a lot, you can blush it to cover it up using pastels. But if it is all over, I think dyeing might be your only option. If you don't want to tackle it yourself, you could look into other people offering the service, perhaps? I am not really aware that it doesn't last if it is done right, though... going from what some doll modders have had to go through to restore dyed dolls back to their original color, it seems to be quite permanent. There are tutorials on dyeing in the workshop --> customization forum if you'd like to read up on it?

 

New I've dyed a couple resin dolls, and dyeing is very permanent - you have to sand off the top layer to remove it.
Dyeing does fade on PVC/ABS/vinyl dolls, and quickly (within a year, the color starts to fade).

For a tan doll, you're going to want to choose the color opposite the one you don't like on the color wheel (scroll halfway down). So if your doll is turning green, using a pale red or orange-red dye overlay will create more of a brown effect.

I see you don't have marketplace access yet, because there are people who offer dyeing services on there. I would recommend going to workshop/customization. Dyeing isn't really that difficult, just fiddly. Also, I strongly recommend that you be precise with your measuring. Just as you wouldn't dump an entire bag of flour into a bowl to make a cake, don't dump an entire bottle of dye into a pan of water - you're wasting dye and aren't going to achieve the result you want.

Editing to add: this thread might help?

 

New Just want to add that I have had (and still have) some dyed resin bjds (bought second hand and dyed by another) and the dye was easily removed. I used acetone free nail varnish remover and isopropyl high percentage. I do remember a hybrid though where the resins were different. The head kept a slight tinge of purple
