This is to the same tune of Arabella's colour being light pink, but MC's colour is definitely pastel blue in my head. Yes I know there are canon characters with blue as their thing, but pastel blue on MC looks so good! Sure, I permit the occasional divergence kinda like how Arabella can go for simple black and white and still work. Pastel blue just translates to MC for me.
