Design a 4K 3D render featuring the phrase "Black Friday" in a striking, bold font. The text should be the centerpiece of the image, illuminated by high-contrast lighting that creates a sense of urgency. A dark theme should dominate the background, while colorful confetti in gold and silver cascades around the text, enhancing the festive mood. Ensure the text is in sharp focus, with a slight blur in the background to draw attention to the message.
