Another thing I like about Cross Saber is how there's almost a progression of his forms getting bluer and bluer as he grows in power (similar to how hotter flames burn blue!)

Like, going from Brave to Crimson there's mostly just more red, but then Dragonic Knight moves the red to an accent color and is mainly silver, which isn't blue but it is a much "cooler" hue than red.

Primitive continues this by confining the red to a few specific parts and instead being mainly a pale blue-white, which makes a nice bridge between Dragonic Knight's silver and Cross Saber's bright blue.

Elemental disrupts the pattern a bit by bringing back the red, but it keeps some of Primitive's blue-white color and leans into the "blue flames" aesthetic, even keeping his eyes white with instead of returning them to their original red-orange color.

And finally, Cross Saber goes to a full bright blue with white sparkles, and red only showing up on the sword's emblem and the tips of his eye flames.

It's kind of neat when you look back on it.
