I saw Zultanite, a rare #gem in #Turkiye that undergoes the #Alexandrite #colour change effect:
Our cones are not created equal; the short 'blue' wavelength sensor is well separated from the similar 'green' & 'red' curves 👁️
Alexandrite cuts off blue (like a yellow object) but embedded metals absorb the middle spectrum, meaning in black-body curve candlelight the 'green'/'red' ratio gets miscorrected by our colour constancy mechanisms🕯️
