'Glasz' eyes, a combination of green, blue, grey, and gold. This eye color (or combinations of colors) has very little melanin (i. pigment) in the epithelial iris layers. The eyes appear to change colors depending on the lighting or surrounding colors.
In this photo I used coral photo paint to change the color of the iris. In order to make this work I chose a lense called Matiz/Saturación/Luminosidad. Then I erased everything around the eye. The iris color originally was blue.
