In "Super Mario Bros.", the clouds and bushes have the same artwork and are just different colors.

The statement is true because in Super Mario Bros, the clouds and bushes are indeed represented using the same artwork with just different colors. This design choice was likely made to simplify the game's visuals while still creating a visually interesting and immersive environment. By using the same artwork for both elements and changing only the colors, the game designers were able to save memory space and optimize the game's performance on the limited hardware of the Nintendo Entertainment System. This approach also allowed for a cohesive and consistent look throughout the game, enhancing the players' familiarity and immersion in the Mushroom Kingdom.
