Let's be honest, due to the new battle lighting changing with the time of day thing they intoduced in X&Y and with various sprite color brightnesses in each new generation we all have at least 3-8 pokemon we've instinctively caught because we thought they were shiny because we can't remember what the shiny version looked like on serebii, and are way too lazy to go and check.
Post the pokemon you keep thinking are shiny but are not and catching here.
I think my recent ones have been maractus, something in that area in pokemon white where you can catch landorus, and magmar.
Also, before someone says garchomp, these are for pokemon you can hatch/catch and you think are shiny and instantly catch/label as holy crap, shiny via the nickname, not the other way around.
