Stacked & Bold Lettermark Logo Prompt Variations

Create a series of logo prompts that focus on a lettermark with large, thick sans-serif initials [INITIALS] positioned on a solid background in a chosen color [COLOR]. All designs should be vector-based, with no shading or gradients, on a pure white background, ensuring they are crisp, high contrast, and perfectly suited for die-cut sticker formats. Emphasize simplicity, boldness, and clarity in every prompt to produce clean, professional results.
