श्वेततारभागौ द्वावेकस्तपनीयस्य मुद्गवर्णं करोति ॥ कZ_०२.१३.५४ ॥
śvetatārabhāgau dvāv ekas tapanīyasya mudgavarṇaṃ karoti
Two parts of white silver (śveta-tāra) with one part of refined gold (tapanīya) make a ‘mudga-colour’ (a greenish gram-like hue).
Colour terms provide a practical taxonomy for inspectors and merchants in marketplaces where formal fineness testing may be limited.
