The decorations use zari (brocade), beads and sequins as raw materials which are sourced from within the city and Mumbai.
Seconding the accessory-makers are the idol-painters, for whom the eco-friendly paints are proving a bit too expensive.
Lead-based paints, which are hazardous to both human health and the environment, have been the staple of the Kumartuli artists for decades.
"We use whatever comes in handy. Given our busy schedule, any paint that's available in sufficient quantity and within the budget is given preference and so far the lead-based paints are the clear winners," said Babu Pal, the spokesperson of Kumartuli Mritshilpi Sanskriti Samity.
Non-lead-based paints, a recent addition, have had a slow start with the artists.
"The price of one eco-friendly paint can is almost twice as much as the lead-based ones. And the suppliers have provided just about five litres of such paint to each artist for free.
"We need around 20 litres to complete one set of idols. That means we have to purchase the remainder with our own funds. It is impossible for us to do so," rued Pal.
Despite the hurdles, eco-friendly paints definitely signal greener pastures.
"We have no objection to using the new variety of paints. Our customers also look forward to such innovations. We have requested the suppliers to reduce the cost, but the government has to stop or limit the manufacture of lead-based paints to have a substantial effect," said Pal.
