Okay I'm just going to say one more thing then I'm done. Those are two bad examples. Vegeta wearing pink is funny because he's not the type of character to wear pink. As for Red VS Blue it's not meant for Kids and Doughnut wearing Pink pretty much lead to another running gag that Doughnut was gay. Decade is always pink so that means if he was the Rider who was adapted they would make a pink joke every episode and it would get old very fast for both Kids and Tokusatsu fans. It's like all the horrible nostalgia references that Power Rangers Samurai makes (Which really makes me glad I kept forgetting to watch it). Ask yourself do you really want Pink Jokes in every episode?
