Based on your description, I would suggest the following color palette for your website:

1. Black (
                            
                            #000000
                        ): This will be the predominant color used for the background, creating a sleek and elegant look.

2. Purple (
                            
                            #8F00FF
                        ): This color will accompany the content, letters, and elements on your website, adding a touch of sophistication and complementing the black background.

3. White (
                            
                            #FFFFFF
                        ): White is a versatile color that will provide contrast against the black background and can be used for text and other elements to ensure readability.

4. Gray (
                            
                            #CCCCCC
                        ): A light shade of gray can be used as a secondary color to create subtle divisions between sections or to highlight specific elements.

5. Pale Pink (
                            
                            #FFD1DC
                        ): This soft pastel color can add a feminine touch and serve as an accent color for certain elements or buttons.

6. Gold (
                            
                            #FFD700
                        ): Adding a metallic gold color can bring a sense of luxury and elegance to your website. It can be used sparingly for highlights or decorative elements.

Overall, this color palette combines the simplicity of black and white with the sophistication of purple and the softness of pale pink and gold. It will create a visually appealing and aesthetically pleasing website that aligns with your requirements of being simple, elegant, and aestheticized.
