Neon-illuminated gaming controller rendered with gradient lighting effects

Digital rendering of a PlayStation 4 controller displaying precise neon gradient lighting applied to the grip surfaces. The left side features yellow-orange luminescence transitioning to red tones, while the right side exhibits cyan-to-green color gradients. Technical execution includes defined button outlines in contrasting colors, dual analog stick geometry rendered with concentric circles, and flat black background to isolate the subject. Lighting methodology employs directional neon effects with smooth color transitions along grip perimeter.
