Yeah, I don’t know about this chart. My Santi is solid black but with pale gold eyes. According to the chart, his eyes should be orange, green, or copper.
That’s the fun of photoshop. 
The colors have been boosted in that photo.
I forgot to say we have a black on grey mackerel tabby with light green eyes. She isn’t letting me look at her pads. I don’t have any pictures of her on the internet right now.
I can tell that, but it’s still weird to have orange/golden fur and blue eyes.
