Anyone got an accurate picture to demonstrate this color?--Light current 20:05, 25 September 2005 (UTC)
This should probably be merged with Lead(II) chromate-- 24.19.194.18 02:30, 27 June 2006 (UTC)
Cadmium pigments have not been replaced by azo on artists' pallets. They are not interchangeable, as cadmium is opaque and azo transparent. — Preceding unsigned comment added by 75.36.151.166 (talk) 00:22, 15 October 2014 (UTC)
Darkening in air
[edit]"Because the pigment tends to oxidize and darken on exposure to air over time" - there is nothing to oxidize here. But reduction can lead to darkening. Further: It reacts with hydrogen sulfide like other lead pigments. --FK1954 (talk) 17:28, 22 July 2018 (UTC)
- Reduction and darkening can occur with sulfur dioxide, the colour changes to green (Chromium(III) oxide). Good quality pigments were coated to avoid contact with both the gases. --FK1954 (talk) 17:50, 22 July 2018 (UTC)
