Okay so headcanon time: The Tears of Princes all had different mothers, hence the varying hair colors
Prince Red’s mother, being feisty and living for the thrill of battle, didn’t settle well with the public. She loved her family dearly, but feeling like she couldn’t stay where she wasnt wanted, she left on her own accord, leaving Prince Red with his father
Prince yellow’s mother hailed from a Noble Family in a neighboring kingdom, so she was much more dignified and calm, if not a little stubborn (and a bit picky about her appearance). Some years after Prince Yellow was born, her kingdom was razed, and she had to leave to go lead/protect it—she left Prince Yellow behind to keep him away from the danger
The final Queen, Prince Blue’s mother, was actually a Commoner, playing music in the streets for money. She was very lively and a nature lover, and was around in the family for the longest. Unfortunately, she became ill and passed away, leading to the king’s descent into greif and madness, and affecting the family very deeply
there’s alot more that i would go into but tumblr is slow as heck and its taken me almost an hour to just type this, so i’ll leave you with that.
