Modify the 3D logo icon for an online English tutor: change the color palette of the four glossy square interlocking gear segments to vibrant colors: coral red, electric blue, lime green, and golden yellow. In the center is the stylized silver letter 'E' as the axis of rotation with soft metallic highlights. On each segment, maintain the minimalist embossed icons for speaking (sound waves/mouth), listening (headphones/ear), reading (open book), and writing (pen). Below the icon, create prominent 3D voluminous extruded typography text in vibrant blue that reads 'CoolEnglish'. Smooth glossy plastic material, soft studio lighting, clean solid white background, isometric view, modern friendly high-tech brand identity, 8K resolution, detailed octane 3D render.
