Amber & Yellow & Blue

Yes — amber, yellow and blue go together as Delft neoplastic primary — honey-amber horizontal flash, solar yellow vertical light, and pure blue spiritual depth in one De Stijl grid. First impression is delft-flag clarity — softer than orange-yellow-blue Rotterdam neoplastic primary, built for sport civic and education. Blue, yellow, and amber each hold a primary corner so the mix reads as complete color with neoplastic weight, not a blend. Picture a national flag stripe, a school banner, or a team kit that owns all three primaries from across a plaza and keeps Delft gravity. Sport and civic brands lean on this triad for universal recognition with Dutch modernist history. Keep one tone as the large field — equal blocks tip into vibrating costume. Delft primary: strong for flags and sport, weak for soft spa.
