| 10 | + Brand : #2563EB Temperature : cool |
| 11 | + Generated : 2026-07-21 |
| 12 | + Method: every neutral surface is blended a few percent toward the brand |
| 13 | + hue, so the brand "flows through" the system instead of sitting on top. |
| 14 | + No pure #FFFFFF / #000000 / #808080 anywhere. Text on each surface is |
| 15 | + checked against WCAG AA and nudged if needed, so readability always wins. |
