Why notorious? It has been said, and repeated many time, that this paint was made in a vile process by feeding cows in India with certain types of leaves, that turned their urine yellow, and this was the foundation of the paint. In addition Rowney and one or two others called it `Indian Yellow, supposedly a replacement for the notorious original Indian Yellow. Both have already reformulated with a multi pigment mix. Although not offered by a huge number of paint makers PY153 was the pigment used by both Winsor & Newton and Daniel Smith for the popular New Gamboge paints. As has been pointed out previously makers of watercolour or other types of paint are very much at the bottom of the pile and have to take whatever is available. “In 2012 the popular pigment PY153 Nickel Dioxine Yellow was discontinued, no doubt because of lack of demand from the chemical and/or auto industries. PY153, bright tranasparent indian yellow color, nickel dioxine yellow pigment is also discontinued. It is sad to hear that PG50 now is not available for artistic use. Therefore, Golden replaced it with actual pigments. Pigment manufacturer discontinued Cobalt Titanate PG50 production. But if they do eventually offer the Titan Green Pale in their Heavy Body acrylics I will give it a try. I was thinking about getting the Cobalt Titanate Green…as it wasn’t as expensive as the other cobalt colors, and I like the light, somewhat pastel look…my colors usually end up too dark and heavy so this would be a useful color to have. I don’t use Open, so the Titan Green Pale replacement is not an option for me. But I chose to post them without any Photoshop color modification…because if I tweak the colors to look more ‘just right’ on my display, it might make it more ‘off’ on other people’s displays.ĪJ, it’s too bad the Cobalt Titanate Green is no longer available. On my monitor, my samples look accurate in terms of hue, but a bit greyer than real life. I suppose it’s possible that the Blick samples might look more accurate on some displays…and mine less so. The information below is accurate as at the time of the listing on-line for the taxon. The IUCN conservation status is assessed globally while the RDB2 and RDB3 conservation statuses are assessed locally. You may find information regarding the International Union for Conservation of Nature (IUCN), Red Data Book version 2 (RDB2) and Red Data Book version 3 (RDB3) conservation statuses. The following table lists the species in this taxon assessed under the Singapore Red List, which is intended to be published in the third edition of the Singapore Red Data Book in future.
