Well, you've definitely got something wrong with your eyes. I can see how lighting and different video hardware might make that second picture appear yellow (definitely green to me), but there is just no other explanation for you seeing the cartoon Constructicons as anything but green. Have you ever played with one of the many online colour-blindness tests just for shits and giggles? Might be worth having a go some time (and then following up with an optometrist depending on the outcome). You're looking for the phrase "deutan colour vision deficiency".
Oh i know I'm colourblind. Have done for the past 30 odd years. We discovered it when playing a game called mastermind where you have to try and guess which 4 colour pegs a player has and which order, and i kept putting the same colours in each guess even though i was told they were a wrong guess, swearing they were different colours to my last guess. Went to the optician who confirmed it. That's why with traffic lights, i stop on the top and middle red lights and go on the bottom white light. And i refuse to drive in a country where the lights are horizontal instead. Also, I'm terrible at those magic eye puzzles.
If Grapple was Orange in G1, then Sunstreaker was "Orange". And if that's the case, then these emojis are "Orange".
