1st new blue shade found in 200 yrs to be turned into crayon
A new shade of blue accidentally discovered by India-born Professor Mas Subramanian in 2009 is being turned into a crayon by US-based company 'Crayola'. The discovery of 'YInMn' blue pigment was made while oven-heating chemicals over 1000ÂºC. The bright blue shade was the first new blue pigment to be created since a French chemist discovered cobalt blue in 1802.
