Random Transformers Headcanons
transformers can see more colors than humans can. Cameras use something called the bayer color filter, which is a grid of red green blue squares that is taken and pixelated- by the same principles, optical sensors could have multiple color receptors (like add magenta and yellow)
Bots with more than two optics can pick up more colors (shrimp vision). Empurata victims lose color receptors in their optic, reducing vision to standard RGB
Depending on modifications, can see in UV, infrared, heat vision, etc. Earth is a sensory overload at times.
Giant seekers like shuttles and space stations sing in ultrasonic waves, often to communicate and identify, as each has a unique song. They're space whales :D
Some bots have UV paint lines on their armor that glow under certain conditions/in response to their spark feeling strong emotions. Could've been an old fashion fad or simply exposed energon nerving in their plating.
Most bots do not have true gray colored plating- it resembles too close to a dead shell and sometimes, some bots are taken to smelting pits because of this. The most common bots to have gray paint are miners and gladiators because it hides debris and injuries better, but also because it keeps them from having any individual identity. Megatron keeps his gray colors to honor his time as a miner and gladiator.
Seekers only stay to their trines/sparklings when sleeping, but ground alts often seek out large groups for security. When grounders are in new environments, often there will be one bot on watch and the rest huddled together at the camp ground
The lost light actually separates bots because of Magnus being an ass and not understanding sleeping dynamics cause it's been so long since he had his brother
Shuttle bots and larger prefer to sleep in their alt modes with their occupants safely tucked away
(last headcanon inspired by an instagram reel I saw by astragirlxx about sleeping groups of autobots)
That's all I've got for now!!!! :DDD
