It's Cuz Snow/Ice Brick Isn't Just "Brick"Would just make sense because bricks made out of clay or stone are called "Red Brick" and "Gray Brick".
So why isnt Snow Brick called "White Brick" and Ice Brick called "Blue Brick"?
The English language and real world connections are likely the main culprit.why isnt Snow Brick called "White Brick" and Ice Brick called "Blue Brick"?
