Minimalist black and white icon: a rounded square face with slanted eyes and a subtle horizontal smile line.

Here’s a concise, text‑based vector spec you can drop into an SVG or illustrator workflow to build Rio’s super‑minimal line‑art face icon: Overall shape Use a simple, slightly rounded square head outline (soft‑tech, not cartoon round). Keep stroke width uniform and thin (e.g., 1–1.5 pt) so it scales clearly down to 16×16 px. Head outline Draw a 2:1 rounded square (width ≈ twice height) with subtle rounded corners (small radius). No neck, no hair, no background; the head is a standalone, almost geometric mask‑like shape. Eyes Two simple arcs or short curves for the eyes, not full circles. Each eye is a concave upward curve (a “smile‑shaped” line) placed horizontally, evenly spaced. Slight forward tilt (eyes angled subtly upward toward the sides) to read as confident and attentive. Keep eyes small and high on the face so the mark feels bright and modern, not childish. Mouth / accent line Use only one subtle horizontal accent line, not a full smile. A short, slightly curved line just below center, slightly downswept at the ends (a “confident but calm” line). This line should feel minimal and restrained, almost like a micro‑smile or a deliberate, composed expression. Expression and feel Confident & accountable: upright, symmetrical head; eyes open and aware, not winking or exaggerated. Helpful & modern: clean curves, no extra details, no pupils or hair; very close to a “symbol” rather than a portrait. Premium tech: tight, balanced spacing; crisp single‑weight strokes; no fills, Mehr sehen
