The first image is from the manga. His eyes are grey, the anime changed for green, in all other color images from the manga he has grey eyes, the color didn't change there. As for the anime, dunno.
The difference the changes in Mikasa's eye color or any of the other characters are the normal variation you get in any anime because of the different lighting in scenes. Eren's eye color change DRASTICALLY more and it's not even close. Teal, light green, light blue, sea blue, gray, grayish blue, grayish green, and then a deep teal color again.

So, after watching the Anime, I noticed that all the people, who inherited the power of the Founding Titan, eye's change from their original colour to a brilliant purple colour, whether they be royal blood or not, as evidence of Grisha Jaeger.

It adds a sense of segregation between the titans. There is an expression in Japanese "the color of their eyes changed" and from what I understand it means that a person has had a change in one's feelings, similar to saying that they have a different look in their eyes. Anime seems to take that literally and in scenes such as when characters are displaying anger or renewed vigor, their eye color changes.
In the case of Eren, it seems to change. Eren has teal/green eyes in the anime &merchandise, gold/yellow in the chuugakkou, and grey in the manga. It's not just his eyes that's different in different media but his hair too (dark brown in the anime but black in the manga).
Armin's memory of Eren's changing eye color might actually be hinting at Armin being the true hero of the Attack on Titan series! Here's how.

Eren Yeager's eyes turned blue after he awakened the power of the Founding Titan.
This is because the Founding Titan is passed down through the royal family, and the members of the royal family have blue eyes. Eren's eyes also turned blue when he used the Founding Titan's power to activate the Rumbling.
