Small-size readability

• Contrast: yellow mark on black fill — check both dim OLED and bright LCD.
• Silhouette budget: line chart, arrow should remain readable after the store’s rounded-square crop.
• Lettering “Investing.com” must survive home-screen size; thin strokes usually fail first.
• monochrome/detailed/photo/dark detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.2/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing Investing.com: 株式市場, not authoritative store scores.

Transferable design moves

• Keep line chart as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (yellow), not the whole black field.
• This capture’s monochrome/detailed/photo/dark vocabulary transfers best when the same restraint is applied at export size.
