THE CENTER

Dynamic Gradients as Data Visualization

Dynamic gradients bridge the gap between static design and responsive interfaces. When the number of agents changes, or when file types shift, the gradient updates to reflect the current state of the data.
Connection to Core-Flow:
├── Core colors are computed at runtime (OKLCH)
├── Flow gradients interpolate between Cores (OKLAB)
├── Theme changes trigger regeneration
└── Performance optimizations keep it smooth
By generating gradients at runtime with OKLCH/OKLAB, we ensure that color transitions remain perceptually clean regardless of the source data.
