Imagine a logo design ideation process for a black pepper brand named "Piper". The logo should be a combination of text and icon. Use a Serif typography to convey a classic and high-end feel. The icon should incorporate a black peppercorn and an elegant pepper grinder, symbolizing purity and quality. Use the color palette #010D00 for the main elements, #736A5A and #8C8270 for accents and background details, #F2CEA2 for highlights, and #0D0D00 for additional dark tones. Display only the logo ideation process, including brainstorming sketches, rough drafts, selected directions, and refined designs. Ensure all four images focus solely on the logo design stages without any packaging elements.
