What makes the FireRed tileset so legendary is how much visual information it conveys with so little data. The bright, saturated color scheme was a deliberate pivot from the darker, more muted tones of Pokémon Ruby and Sapphire . Because the original GBA lacked a built-in backlight, the developers at Game Freak specifically cranked up the vibrancy and contrast of the FireRed tilesets to ensure Kanto was highly visible on unlit handheld screens.

Add some details like flowers (if flower tiles are available) or a decorative stone (if such tiles exist) near the pathway to add more visual interest.
