From the uploaded image guide, generate a set of 6–8 simplified human face profile silhouettes for a logo. Preserve the exact color palette from the guide. Each silhouette uses a bold, clean contour with no facial features or shading, consisting of flat fills for a scalable, brand-friendly look. Include left-facing and right-facing variations and explore different profile shapes: varied jawlines (square, rounded), nose bridge styles (straight, slight curve), chin prominence, and hairline silhouettes (short cropped, long flowing, shaved). Keep compositions balanced and minimal, suitable for vector logo usage. Output ready in vector-friendly outline form with crisp edges and solid colors on a transparent background.

The image shows a black and white logo with the word "Kivuli" in the center, surrounded by silhouettes of people's heads. The logo is set against a white background.
