Owner review 5, lane I: brand mark proposals (2026-10-12)

Status: Draft · Date: 2026-10-12 · Lane I of owner review 5, point 6. Inputs: the mark brief (R1 to R10) and the four concept directions in flat-v2-brand-touchpoints-2026-10-09.md section 11, the brand board, and the store icons of the peer apps fetched on 2026-10-12. Board: /wireframes/flat-v2-brand, section "Mark proposals".

Owner, review 5. Point 6: "When you get a chance, please propose a few marks that suit our audience and brand."

0. Evidence tags and limits

Tag	Meaning
C	Read in our code or docs, with path:line or section.
W	Fetched on 2026-10-12: App Store icon artwork through the iTunes search API (artworkUrl100, viewed as images), and the Apple and Android pages named in the text.
X	Not reached, said so. The Apple HIG fetch returned a summary, not the page; the web search returned nothing on Playtomic, Strava, Nike or 당근 marks, so those rely on W images only.

No claim here rests on one source for a number. The numeric rules (66 of 108 dp, 68%) are the ones already adopted in the brief and cross-checked there.

1. What peers draw (W, icon images, 2026-10-12)

App	Construction (seen in the store icon)	One colour?	At 16 px
토스 (Toss)	Abstract blue form, no letter, no ball; shape only	Yes, blue	Reads
당근 (Daangn)	Orange carrot with a green leaf and a location-pin cut: a symbol	No, 2	Reads
배민	배 monogram in two tall bars on mint, a Hangul letterform	Yes	Reads
네이버 밴드	Lowercase b letterform inside a ring, on green	Yes	Reads
숨고	Hangul wordmark on a speech bubble: text	Yes	Weak
Playtomic	A "P" letterform with court lines, on blue	Yes	Reads
Strava	Two stacked chevrons on orange: a pure symbol	Yes	Reads
Nike Run Club	The swoosh with the word RUN: a symbol plus text	Yes	Weak (text)
SwingVision	Tennis ball with a seam on green: a stock-ish ball	No, 2	Reads
UTR	A "U" ring with a ball arc, on black	Yes	Reads
ATP WTA Live	The words ATP WTA LIVE in a frame: text	Yes	Weak
Tennis TV	Ball with a play triangle on a lime tile	No	Medium
테니스프렌즈	A glossy realistic ball: an illustration	No	Medium

Reading: the marks that last are one letterform or one symbol in one colour (배민, Band, Playtomic, Strava, UTR); the Korean community apps use a Hangul letter (배민) or a lowercase letter (Band). Ball illustrations (SwingVision, 테니스프렌즈) are the tennis category's default, so a plain ball mark is generic and sits among them. Text in the icon (숨고, ATP) is the weakest at small sizes. Toss's own newer symbol is described as blending a message gesture and a tossed ball (Design Compass, 2022), one source, not cross-checked.

2. Icon rules the marks are built to

• Android adaptive: every layer 108 dp; the outer 18 dp is masking, a 72 dp centre, and a 66 dp safe zone that is never cropped; the logo between 48 and 66 dp; clean edges with no baked shadow; an optional single-layer monochrome icon for Android 13 themed icons (Android Developers, W). Our marks are drawn to one circle that fits the 66 dp safe zone (61.1%).
• Apple: a 1024 px square master, no baked corners, layers, light, dark and tinted appearances, avoid text, flat distinct shapes, no thin strokes under Liquid Glass (Apple HIG, app icons; the fetch was a summary, X on exact wording). Our grid keyline is 68%, ours, since the HIG gives no number (C: touchpoints doc, B1).
• Small sizes: favicon at 16 and 32, notification at 24 dp: one colour on alpha, every gap and stroke at least 2 px at 96 px (C: R2). Strokes in the proposals are 8 to 10 units of 100, which is 1.9 to 2.4 px at 24 px.
• Korean lockups: 투마 beside TwoMore. The board sets 투마 as live text for the proposal; the shipped lockup outlines it as TwoMore is (C: flat-v2-brand.jsx header comment).
• Trademark hygiene: none of the five copies a tennis brand's protected mark; a ball seam and the court's T are generic. KIPRIS search is still required before adoption (C: R8). Nearest peers by silhouette: UTR (ball with a U), Tennis TV (ball tile), SwingVision (ball), Band (letter in a ring). No clash with 당근's orange carrot, which is a different shape and colour.

3. The five marks (drawn on the board)

Each is one flat silhouette in the 100-unit circle. Colourways: on ink, a one-colour mark is ball green-yellow; a two-tone mark is white plus ball. On ball and on white it is ink. The brand green #006D37 appears only in the light notification shade check (accent #02914C there).

#	Mark	Idea	Construction
1	Seam 2	A ball whose seam is a 2: one cut for two and more.	Disc r 50, a stroke-10 numeral 2 knocked out.
2	Toss over the T	A ball tossed over the court's T, which is also the ㅜ of 투.	T of a 17 bar and 17 stem; ball r 16 offset right of the stem (not centred, so it reads as a toss).
3	Four spots	Doubles needs four: two in, two open: 두 명 더.	Two solid discs r 17, two rings (r 13, stroke 8) on a 2 by 2 grid.
4	Bounce	Two arcs and a ball: one rally and one more bounce.	Two stroke-9 arcs and a ball r 11.
5	투 monogram	The Hangul 투 from bars; its ㅜ is the court T, drawn in the ball colour.	ㅌ as three bars and a stem (stroke 9), ㅜ as a bar and stem (stroke 10).

Every mark is shown on the board at the app icon 180 on ink and on ball, at 48, 32 and 16, as the 24 and 48 px notification silhouette on the dark and light shades, and as lockups with TwoMore and 투마.

4. Ranking (decided by evidence, then the owner's taste)

1. 투 monogram. For 30s to 60s Korean club members and a 총무 who says "투마" aloud, the Hangul letter is the most legible and the most ownable, as 배민 shows; the T is hidden in the ㅜ, so the court and the name share one shape. Weak spots: Hangul only, so a foreign eye cannot read it; the ㅌ's three bars leave gaps of about 1.4 px at 24 px notification, so it needs the small master (heavier bars, R9).
2. Toss over the T. The simplest silhouette, holds at 16 px and 24 px, and the T carries Two, 투 and the court. Risk: ball over a bar can read as a person or a division sign; the offset ball is the fix and the owner should judge it.
3. Seam 2. The clearest "two" and instantly a tennis ball, but it reads as a numbered badge or a generic ball in a circle, near SwingVision and 테니스프렌즈.
4. Bounce. Motion is on brand, but it reads as an m or a scribble at 24 px and loses the ball. Weakest silhouette.
5. Four spots. The best picture of recruiting, but it reads as dice or a grid, and the open rings fail as rings at 16 px.

Recommendation: take 1 and 2 forward. The 투 monogram is the safer, more Korean answer; Toss over the T is the more symbolic and international one.

5. Questions for the owner (taste, not evidence)

1. Should the mark be Hangul (1) or a symbol that works without reading Korean (2)? This is the one real fork.
2. Should the icon carry the ball colour on ink only (one colour), or white plus ball (two tone) as drawn for 1 and 2?
3. Is a ball plus T that can be misread as ÷ at 16 px acceptable, given the offset?

Implementation

• [ ] Owner picks a mark (or two to refine); then redraw it as the real D1 SVG master (1000-unit artboard, keylines at 61.1% and 68%).
• [ ] Replace FbSlot and the MARK label with the chosen mark in docs/twomore_design_system/wireframes/flat-v2-brand.jsx (FbIcon, FbAdaptiveLayer, FbNotif, FbFavicon, FbLockup), then drop the proposals section and FB_PM.
• [ ] Outline 투마 from Pretendard Bold into FB_WORD, as TwoMore is, for the Hangul lockup.
• [ ] Cut the small master (R9) if the 투 monogram is chosen: heavier ㅌ bars with at least 2 px gaps at 24 px.
• [ ] Export the deliverables of the brief D2 to D8 (apps/mobile/assets, apps/web/app/icon.svg) and run the KIPRIS search (R8).
• [ ] Update docs/design/flat-v2-brand-touchpoints-2026-10-09.md (section 11 notes the options now exist) and the screen blueprint if any in-app mark use changes.
