Small-size readability

• Contrast: pink mark on green fill — check both dim OLED and bright LCD.
• Silhouette budget: rose, petals, leaves should remain readable after the store’s rounded-square crop.
• Lettering “1 2 3” must survive home-screen size; thin strokes usually fail first.
• detailed/illustration detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.4/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing Happy Color® – 数字で塗り絵と色ぬりえ, not authoritative store scores.

Transferable design moves

• Keep rose as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (pink), not the whole green field.
• This capture’s detailed/illustration vocabulary transfers best when the same restraint is applied at export size.
