Sorry you guys...I had to start a new thread for this.It's driving me crazy. First off, I'm not color-blind. I know what colors I see when I see them. But,a few of the newer cats,all related to the Siameezer feral,have got strange colored eyes. Runt,the black former mama in which I still have her 2 black kittens, Has different colored eyes. In the indoors light,she clearly has gold eyes. When I get her out in the outdoor light, she clearly has the deepest lime-green colored eyes I've ever seen. One of my younger foster's,Rusty, does the same thing. His go from dark gold coordinating with his marmalade orange coloring,& then in bright light,they're as green as emerald. So,how do i determine what their true color is?

Color of Cat's Eyes

I wonder if they differ as colors differ under cold white fluorescent vs. warm white fluorescent? Or as colors differ under indoor, warm white incandescent bulbs vs. outdoor lighting?

I don't know about coat anncetera,but,I do know their eyes are clearly green in outdoor light. I love green eyes on cats. BTW...I called Pets & Pals. Bad news. She was telling me that as of the first of the year,they were going to stop accepting cats altogether. I guess this last cat & kitten season were so terribly expensive for them that they can't do it after that. She said they're putting the word out now in hopes that it will stir up some badly needed donations in their direction. She told me to check back with them from time to time to see if the decision changes. We discussed other possible alternatives to my dilemma. She told me what I was afraid she would. The only other no-kill shelter in the surrounding cities within our county is Delta Humane Society. I know they mean well at Delta,but,I've seen as many as 5 cats in a 4x4 ft.cage because of their overcrowding situation. I'll just have to keep mulling over things in hopes of coming up with some new ideas. Man/friend is even considering having a cheap covered enclosure put up in our (quite small) back yard to give us some relief from the animals inside & giving them alitle taste of the outdoors. I don't know about that idea since he'll be having radiation treatments soon for his cancer. I'm certainly not letting myself get over-stressed by it. It won't do me any good. Hugs

April's eyes turn color too, from light green to almost golden depending on whether it's sunlight or artificial light. But nothing so dramatic, though.
Since color is the result of different wavelengths of light being reflected back (e.g. if light at the green portion of the spectrum is being reflected back the eyes will look green), I'd guess that the color change is just an artifact of the type of lightbulb we use. If the wavelengths of light they produce are very different from those in sunlight, the cat's eyes will reflect back different colors depending on the type of light that hits them.
I say April's eyes are green because that's how they look under sunlight (full spectrum light), as opposed to their golden color under an incandescent lightbulb that doesn't produce the full spectrum of light. Her eyes also look greener under fluorescent light. I'd love to hear a cat expert's take on it.

Part of the eye color in different light is related to the night reflectiveness of the cat's eye.
With a normal coat pigmentation:
The luminous appearance of a cat's eyes in the dark is due to the reflection of light by the tapetum lucidum, which is part of the membranous layer between the retina and the outer covering of the pupils of the eyes. This remarkable layer is distinctly differentiated from the choroid layer only in certain animals. It is the tapetum lucidum that enables members of the feline family and other nocturnal animals to see even when there is very little light. Some authorities believe this layer reflects the light rays through the retina a second time. In the domestic cat the tapetum lucidum is brilliant green or blue in color and has a metallic luster. The well known glare is especially noticeable when artificial light is thrown on a cat in a dark corner, or when a cat in a dark place is observed through an opening, light entering the darkness through the opening being reflected from the cat's eyes as from a mirror.
Genetic Siamese blue eyes and Albino Pink-eyed cats reflect red.

Thank you, ailuromaniac! That would explain Miss Nib's "glamour shot" on her Catster page, where there appear to be no black pupils at all - everything reflects green! Her eyes always look green, by the way, but different shades of green in different light. I love to look at cats' eyes, all the different beautiful shades.
