Soft Accent & Highlight
With 62% lightness, #DEFF3E has a softer, more approachable quality. It works well for hover states, subtle highlights, progress indicators, and secondary UI elements. This lightness range is particularly effective for tag backgrounds and status indicators.
Attention & Optimism

Gradient Pairing
Create a gradient from #DEFF3E (hue 70) to its complement at hue 250. For a subtler effect, try pairing with an analogous color at hue 100. Use CSS: background: linear-gradient(135deg, #deff3e, #5d3dff);
