If pink and yellow have a thematic importance, what about its inversions? Green and blue.
Green and blue are the colors of Kris and Ralsei's icon sprites. Interesting....
Pink is Susie, yellow is Noelle, Blue is Kris, Green is Ralsei.
Now here's the kinda stupid parts here. You know who has pink and yellow? Catti, how much?Well she has a decent amount of pink, but not a lot of yellow. Only her eyes are yellow. In fact, you could say she's more like pink and black.
Now Jockington. He has a green and blue color pallete. Looking at him, you can see that he is.... primarily blue?????!?!? His clothing takes up a majority of his sprite.
These two, who have the four colors we are talking about in their palette are depicted as friends. People who work together, yadayada.
Now the battle icons?
Blue, green, pink, yellow.
Inverted colors, work together.
I might be pulling out of my ass already, but I'm going to do it more.
If pink and gold are hopes and dreams, what would green and blue represent?
Well that's up to you to decide. But I'll pull my hat on the ring.
Blue is control. Kris is the character we control. The prophecy panels are in blue. Those, for the most part, dictate events. Having control.
Green? I'm not sure on green. Reality? Truth? Those are my best guesses....
Now onto the duo from earlier.
What do their palettes represent?
Maybe that Catti is losing faith. We know she doesn't attend church, despises her parents (or was it her entire family) and such stuff. The colors on her are related to the prophecy. FIELD OF HOPES AND DREAMS RAHHH.
Now Jockington? He will gain more control over the matter. He's an extrovert, the popular kid. He will, somehow, get control.
All this could just be one giant ass pull here, but I just want to get my thoughts out there.
