There are some things that could cause that. The lighting could be the most likely reason why they look like they change. They could also change depending on what color clothes he's wearing অথবা it could also change depending on his emotion.
My eyes are generally grayish coloured. They change to brown, amber, and green sometimes, and hazel (which is brown and green contrary to জনপ্রিয় belief) it usually depends on what Im wearing, but sometimes my mood too. i guess it could also be the lighting and stuff.
Some people's eyes do change রঙ depending on their mood, the lighting, the clothes they're wearing, and other factors. Hazel and grey eyes seem to do this the most often.
When the pupil size changes, the pigments in the iris compress অথবা spread apart, changing the eye color a bit. Certain emotions can change both the pupil size and the iris color. Eye color is based on the pigment (melanin) in your eyes Brown eyes can appear to change color due to less pigment and effects from the exterior environment (clothing, lighting) bringing out specific রঙ more Dramatic changes can indicate ocular disease If that is the case...id suggest seeing a doctor
Maybe His Eyes Are A Mix Of Them. I Have Honey Eyes And There Are Some People Who See Them Exclusively As Green And Few Others Exclusively As Brown !!!!
