In this palette the hues fall in the green, blue and rose families, spread across 249 degrees of the OKLCH hue circle. Dark palettes keep chroma between 0.04 and 0.14, and lightness between 20% and 52%, which is why the set feels consistent.

That combination suits dark-mode interfaces, gaming and music apps and luxury packaging, and it is a good fit when you want a design to feel deep, dramatic and immersive.
