How is ''yellowing'' on TAN resin like?

Depends on the particular resin, but some tans fade to a more grayish tone. Some turn greenish. Some just get more golden, and some don't fade at all!

 

But the yellowing is usually very gradual and shouldn't be anything extreme. There have been problems now and then with certain resins or resin batches, but the colors should keep for quite a while. I've had dolls for 10 years and am not worried about yellowing.

With white skin dolls, yellowing can be a little more noticeable since some dolls come paper-white when new and could change over years to be not as white. But I've had plenty of white dolls that came in more creamy tones when new, so yellowing won't change them as drastically... they will yellow, of course, but maybe just become a bit more creamy.

Tans come in all kinds of shades, too, so they will yellow differently. As Alewife says, the yellowing can make the color seem to shift a bit towards a variety of shades. Greening can happen with all colors, but it doesn't mean you'll start seeing a bright green doll! It's just a slight shift in that direction. (Bright green has happened pretty much only in French Resin light blue dolls, where the blue fades and the resin yellows--so you pretty much have a specific combination. Some early Iplehouse Real Skins had a problem with green spots that were pretty much a dark green--and the company had to offer some replacements. They have since fixed that problem, of course.)

Resin mixes often have some kind of UV protection in them. Sometimes not. But companies try to make sure the colors don't shift drastically or quickly. But many are trying new colors and resin recipes, so problems can happen.

What can most likely happen is that the clear part of the resin will yellow over time, and sometimes some of the color in the resin can also fade a bit. Tans have lots of reds and yellows in the color already. It isn't a light color, so the shift to yellow won't be as obvious as when starting with a very white doll. It's possible that the yellow coloring in tan could fade a bit and might balance out the yellowing of the resin over-all. But the reds might also fade a bit over the years... so that would make the color look a bit more yellow, too.

Just keep your doll out of direct sunlight and direct flourescent light and the yellowing should be very slow--I mean, years of slowly yellowing... (unless you've got a problem doll, anyway). You might not even notice it. Most people who have older dolls that have yellowed evenly can't really tell unless they compare it to a new doll--but that resin color could be different to begin with!

I wouldn't worry about yellowing. Unless there's a problem with the resin or you have your doll exposed to a lot light for days on end, it shouldn't be anything you'd notice unless you are very, very good at catching slight differences in color.

 

I have to agree with what has been said above. It will vary by company because each company will have different mixtures for their resin and colors. Personally, I have two Iplehouse dolls, one in Real Skin and one in Light Brown. Their color seems fairly stable and I haven't noticed much difference in them.

That said, I also have to agree that all dolls will yellow eventually. It is just a fact of the hobby due to the materials being used.
Yes, you can minimize it by taking care of your doll and keeping them out of light, but it will still happen. I have had dolls that have been stored (unused) in a dark closet that still were mellowed when I took them out after months just because the resin itself aged and settled. Just because of the composition of the resin. Once the settling happens though, the resin color should be pretty stable and the color that results from this kind of yellowing (you often hear it called "mellowing") is usually quite pleasant. It's much more a creamy ivory tone. I have some dolls that I actually prefer the mellowed tone over the original (to me) overly pink tone. Hehe.
Anyway, just a frame of reference. ^_^

 

I was thinking more about this... I think tan has a good chance of SEEMING to yellow a bit LESS because it has so much color put into the resin that you won't be able to see the clear/white part of the resin quite as much as in white or normal, which has very little pigment in it. Of course--there is the color-fading that MIGHT happen, but companies try hard to make the color as light-fast as possible.

Example: French Resin colored Bambicronies, that were made like 7 years ago... French resin recipes back then were very transparent and yellowed easily (no UV protection then). So I have a Misty Blue one that has shifted from a turquoise color to more of a green because it was VERY transparent with very little color in there. And the blue that was mixed in faded quickly. Some people ended up with pea-green Misty Blues. But mine isn't that bad at all. And others haven't yellowed badly, either, even though it definitely was a problem-recipe as far as yellowing. The Rose colored dolls also yellowed and the pink faded, so they turned into a more peach color. But the Slate Grey color, that had a more opaque color and wasn't quite as pale, my Slate Grey Bambicrony didn't shift color as much.

I'm thinking that most tans I've seen are more opaque (not as transparent) and have more color mixed into the resin, so they might have less of a chance of yellowing quickly. They will still yellow, but it might not be noticed because of all the other pigment that is needed to make the tan color in the resin.

I'm just guessing here, because it all depends on the various resin recipes, but it's a thought.

I think the rumors of tan resin being a possible problem were just because tan resins came after white and normal colors were used for YEARS, and at first the companies had to find the recipes that worked the best for them, so there were a few problems with a few dolls. I really haven't heard of any problems with tan resins (aside from maybe specific batches, but even then--not a problem with the resin color, just maybe a bad mix in one pour)... I really think tan resin is pretty stable these days.

As stable as any resin, anyway!

 

The only tans I've seen in person that turned color were a 7-year-old Supia light tan, and a first issue Iplehouse EID real skin. Both had French resin in the formulation, so that was probably the culprit. The red color faded, leaving a more grayish/yellowish color behind. However, I have 3-year-old tan dolls that have not changed color at all.

 

Does anyone know something about sunlight skin from Volks? Does the skintone change the color?
Someday I plan buy a doll in this skin tone, so if you can write about this

 

I have owned many tan dolls, but not really noticed any color change. My oldest is Jayden, he's a Jie Doll Michel in chocolate skin, enviro resin, and almost 3 years old. I haven't noticed any color change in him, he's still the dark, rich brown he was when I got him. I also own a tan Island Doll (two years), and don't see a change in him either. French resin may change drastically, but translucent enviro doesn't seem to have a problem, from what I've seen.

 

It all depends on the company's method of making the doll tan. Some companies dye their dolls and some actually put pigment in the resin. I have a planetdoll Roseanne that accidentally got left in the sun (bad doll mommy!) and she faded in places and got less tan. I'm modding her right now and was able to sand away the tan so I'm assuming planetdoll dyes their dolls. But yeah it all depends on the company.
