existing colour palette enhance the backlighting behind the cera letters and behind the dark blue polygon shape to appear more realistic even and defined use a consistent colour temperature across all backglow elements the current render mixes two different white colour temperatures the glow should match uniformly throughout the design restore and enhance the backglow behind the dark blue polygon shape ensuring it is visible and integrated naturally into the scene the glow should softly wrap around the edges with realistic light diffusion and subtle falloff onto surrounding surfaces the cera letters should maintain their current appearance and scale but with a cleaner more premium looking halo effect that feels physically accurate as if illuminated by concealed led backlighting avoid overexposed or blurry glow effects
