Same is the case with my eyes too. In the morning (around 9.30 am), dark chocolate brown (almost black), but in sunlight or artificial light, brown (the pupil is clearly visible as black, and the iris is brown with brown-black specs and a black halo around the brown iris). How and why do the eyes appear differently under different conditions and intensities of light? How is the real eye colour then determined?

The real eye color would be whatever color they appear in natural light. Artificial light can sometimes make things appear a different color that they are in natural light.

There is no scientific concept of "real eye colour." For terms of ID, we generally put whatever of the five main eye colours it is closest to. The five colours are Gray (no blue in any light except maybe blue light,) Blue(may have some brown or gray), Green (no brown), Hazel(brown with green) and Brown. Some IDs also include Fawn, which is a pale brown.
Contact lens companies create dozens more colours.
Sometimes a genetics text book or intro sci text book will pretend blue and brown are simple dominant/recessive allelles for the purposes of explaining heredity, but eye color in humans does not work like that.
