Harmony: Tonal Accent

One color is neutral and the other carries the chroma, which is a reliable formula for balanced design. The neutral gives the eye somewhere to rest while the chromatic color provides the focal point.

The hue angle between Black and Lime is 85 degrees (though one or both colors are achromatic, so hue angle is less relevant than lightness contrast). You can explore these relationships interactively in our Color Wheel Tool.
