CASTANEDA DELGADO, María. Indigo in Novohispano Easel Painting: Deterioration Mechanisms. Intervención (Méx. DF) [online]. 2019, vol.10, n.19, pp.25-35.  Epub Mar 20, 2020. ISSN 2007-249X.  https://doi.org/10.30763/intervencion.2019.19.206.

Indigo is a pigment of plant origin that has been historically used as pictorial material in oil pain ting. Recent material studies of viceregal easel painting have shown its relevance on the blue pa lette, mainly on works from the 17th and 18th centuries. This RESEARCH reviews the relevant bibliography for conservation in relation with the definitions of indigo and its composition, as well as relevant for its agents and mechanisms of degradation. It is important that in the preservation of easel paintings the presence of indigo is identified and that its sensibility to atmospheric factors, specifically oxidizing agents such as ozone and light, is considered.

Keywords : indigo; paint; discoloration; diagnostic; deterioration; viceregal art.
