"Create a square logo with rounded corners. The logo should be minimalist, with a clean and modern design. Inside the square, prominently display the letters 'C’ and 'C' in bold, white typography. The background color should contrast with the white letters, such as a deep blue, black, or dark grey. The letters should be well-balanced and positioned centrally, maintaining symmetry and clarity. Ensure that the logo has a professional and sleek appearance suitable for branding purposes." --s 250
