Amber's eyes are actually more brown than orange, though they could be considered as falling in both categories, while Cinder purely had orange-yellow eyes.

But yeah, eye colour does not have anything to do with what type of Maiden you are from what we've seen. It's not like the Fall magic power is going to think to itself "Whoops, previous host died. Now, where's a nice orange eyed girl to go to. Oh, the previous Maiden thought of an orange eyed girl? Awesome!"

That's...not how magic works.

And I think if their was an eye colour trend, Ozpin and Co would have mentioned it when they told Pyrrha about the Fall Maidens. They would have noticed if every Fall Maiden had orange eyes after all, and mentioned "Oh, seasons seem to prefer girls with a particular eye colour depending on the season." And if that was the case, Ozpin and Co wouldn't have picked Pyrrha to become the next Fall Maiden, as she had green eyes. They would have picked another girl with brown/orange eyes (such as Velvet, or Blake. Or some random other student we haven't been introduced to).

Eye colour is not an indication of Maidenhood. It's something that your genetics decide, and the character concept designer decides, who probably doesn't have any of that sort of information. She probably just makes the characters based on a few ideas Kerry and Miles throw at her without knowing any sort of special information like that.

(And about Ruby having silver eyes which are important, so obviously the design artist must have known; Monty designed Ruby. And Pyrrha. And a lot of the others. Then the design artist took his ideas and remade them, but kept a few of the original ideas, like Pyrrha's red hair.)
