Note though, that this extra restriction isn't a technical limitation of the NES, rather, it's a choice by the developers of Legend of Zelda for the purpose of shrinking the amount of bytes needed for each "screen" of the world.
By doing this, you only needed to store 2 palettes per "screen", rather than 16 tiles x 11 tiles = 176 palettes per "screen".
