* there is inconsistent and confusing literature and information on NY13 and NY14. Many sources seem to use both interchangeably.

It appears that most often what is called Natural Yellow 14 (NY14), is what was originally called "still de grain" made from Buckthorn Berries (Rhamnus catharticus).
But, later, after appox. 1819, the pigment extracted from Black Oak was called "still de grain".

As far as I can determine, It seems Natural Yellow 13 (NY13), most often refers to that made with Black Oak and Quercitron as the main coloring matter. (Ref: Dutch Pink, CAMEO Materials Database MFA, Boston);
(Ref: Color Index Constitution Numbers Third Ed, 1998, numbers 75430, 75640; 75650; 75660, 75695; 75700; 75710;),

** Pink in this sense refers to a yellow pigment based on natural yellow dyes, usually the lake of an extract from Buckthorn Berries with the but may have been used for other dyes based on Quercitron. The word pink came into use during the sixteenth century;
According to the 2008 version of the Pigment Compendium, "there is speculation that because of the yellow color, it is derived from the German "pinkeln" translated in a dictionary of 1798 (by Adelung and Schwann) as ‘to piss, to make water’." (Reference Pigment Compendium, 2008, by Nicholas Eastaugh, Valentine Walsh, Tracey Chaplin and Ruth Siddall)

***Color depends on ripeness of the berries and precipitant; Deep yellow lake on alum and yellow brown on carbonates (Reference: A practical treatise on the manufacture of colors for painting, 1874, also see the Free Art Books page under Pigments, Art Conservation and Art Materials.)

If Indian yellow did come from cows urine, the common claim that they were cruelly "force fed" mango leaves is probably false. Mango Leaves are high in minerals, vitamins and protein and also anti-viral and antibacterial. Mango leaves may have been a perfect feed for cattle and not "cruel" at all (Ref: Feeding Value of Mango Leaf (Mangifera indica) for Growing Rabbits, Journal of Animal and Veterinary Advances, 2006, Vol: 5, Issue: 10, Page No.: 800-804),

Avoid dust & spray, do not ingest, do not heat.

Soluble Cadmium levels are kept below 1 part per million, not considered toxic in normal usage (Ref. The Artist Handbook revised edition (2003) p.19 by Ray Smith)

According to the ECHA, no hazards have been classified for Cadmium zinc sulfide yellow: (Ref. ECHA European Chemical Agency)

Note: Cadmium pigments are nearly insoluble in water, limiting their potential toxicity. They are carefully engineered to meet extremely low solubility limits.
"A risk assessment of these products conducted by the EU concluded that these products offer no significant hazard to either human health or to the environment."
(Ref. Cadmium.org)

Soluble Cadmium compounds can be toxic if ingested or if the dust is inhaled, they are a known reproductive and developmental toxicants.

It is overall a less costly pigment but some colormen make no distinction and charge the same as if it were PY35.

Cadmium-Barium pigments can be up to almost 60% barium sulphate. (Ref: Painting Materials, A Short Encyclopedia, By Rutherford John Gettens, George Leslie Stout)

?* on the Grumbacher website and on Blick Art Materialss site, Grumbacher Cadmiums are indicated to be PY-35, However the Grumbacher web site also states they are "coprecipated with barium sulfate", that would make them "Cadmium-Barium" versions of those cadmium colors and should have a :1 after the color index name. (ie. PO20 should be PO20:1). Older Grumbacher literature do indicate these are Cadmium-Barium colors.

* Requires a PROP 65 label in California.

Avoid dust & spray, do not ingest, do not heat.

According to the ECHA, no hazards have been classified for Cadmium yellow: (Ref. ECHA European Chemical Agency)

Note: Cadmium pigments are nearly insoluble in water, limiting their potential toxicity. They are carefully engineered to meet extremely low solubility limits.
"A risk assessment of these products conducted by the EU concluded that these products offer no significant hazard to either human health or to the environment."
(Ref. Cadmium.org). Older paints made before 1980 may have less stringent standards.

Soluble Cadmium compounds can be toxic if ingested or if the dust is inhaled, they are a known reproductive and developmental toxicants.

"Lead antimonate yellow or Naples Yellow is one of the most common yellow pigments in Western European art. It was used mainly in the period from 1500 to 1850. During the 18th and 19th century a whole range of production recipes were published." "Under the nomenclature of potters' yellow the recipes describe some production details of the pigment." For the recipes and other information see:

** Requires a PROP 65 warning label in CA. CONTAINS LEAD. HARMFUL IF SWALLOWED. Avoid ingestion and skin contact. Avoid dust. Keep far out of reach or possible contact with children & pets.

It is a very bad idea to spray or airbrush lead pigments, even if wearing a dust mask and protective clothing, the overspray would be a nightmare to clean up and would contaminate the whole spraying area.

Lead and Antimony are both toxic if ingested or inhaled. Toxic effects can be accumulative.
Usually substituted with less toxic pigments and mixtures in modern paints, genuine Naples Yellow is still available from some suppliers, (see links in the marketing & common names column).

There are many other names for ochres and yellow hydrated iron oxides, usually based on color hue, production location or manufacturing method, followed or prefixed by other properties such as raw, burnt or transparent etc. There are also many different traditional spellings of the word Ochre, Ocher, Ocre, Oker, Oaker, etc. There are also variances on the words oxide (Oxyde, oxid, etc.), Iron (di ferro, de fer, mars, Ferric, ferrous, etc.) and yellow (amarillo, juane, geel, gelb, lemon, citron, mustard, etc.). The yellow iron oxide pigments have an ancient history and because pigments often still use the traditional name, a multitude of languages have intermixed and the different names have become an almost impossible list of varied phrases.

There are many other names for ochres and yellow hydrated iron oxides, usually based on color hue, production location, mining site, or manufacturing method, followed or prefixed by other properties such as raw, burnt or transparent etc. There are also many different traditional spellings of the word Ochre, Ocher, Ocre, Oker, Oaker, etc. There are also variances on the words oxide (Oxyde, oxid, etc.), Iron (di ferro, de fer, mars, Ferric, ferrous, etc.) and yellow (amarillo, juane, geel, gelb, lemon, citron, mustard, etc.). The yellow iron oxide pigments have an ancient history and because pigments often still use the traditional name, a multitude of languages have intermixed becoming an almost impossible list of varied phrases.

* A few paint brands use mixtures of PY42 and PY 43, but since they are essentially the same chemically, it's virtually a single pigment. This type of mixture is usually done to get a more consistent color from tube to tube, as the natural product can vary batch to batch.

** Oil paints and watercolors using PY42 and PY43 exist in almost any shade of yellow, orange, red and brown.

*** Color, transparency and oil absorption in artist earth pigments can vary widely depending on iron oxide to hydrated iron oxide ratios, clay content, particle size, impurities, additives, fillers, and other mineral content. (Ref: Natural Earth Pigments CAMEO Database at MFA, Boston); (Ref: Yellow Ochre CAMEO Database at MFA, Boston)

**** Natural product could have small amounts of heavy metals, manganese, lead or other trace minerals, any soluble minerals will be washed out during the levigation process so only minute traces of soluble materials would be left, avoid dust.

Said to be a good primary yellow for color mixing in artist paints, although it appears that the light fastness of this pigment is not good in tints and transparent versions. It appears to be rated higher in acrylics which may add some degree of protection? Most paint makers only use it in acrylic or inks.

?* Magnesium Euxanthate is thought to be the main yellow coloring chemical of genuine natural Indian yellow. It is possible (ed. Probable) the urine of cow history of Indian Yellow is nothing more than an myth (see my blog article) and true Indian Yellow is simply euxanthate acid, isolated from a natural source, and precipitaded on a dolomite or other base cantaining magnesium., possibly from a plant source and mixed with magnesia or precipitated on a calcium base. The chemical formula for Vat Yellow 20 contains no Magnesium, the pigment is the Vat Yellow dye preciptated on a base, most likely Calcium carbonate or Magnesium hydroxide.
