What is a vectorscope?

A vectorscope plots the chrominance (color) information of every pixel in your image on a circular graph. The angle around the circle represents hue, and the distance from the center represents saturation. Neutral colors (grays) cluster at the center, while vivid colors extend toward the rim. It is a standard tool in broadcast, cinema, and professional color grading.

Density modes

Scatter

Each pixel is a single dot. Overlapping dots accumulate brightness with additive blending. Best for seeing individual color samples and sparse distributions.

Bloom

Each pixel creates a soft radial glow. Overlapping glows blend additively, creating luminous hotspots where colors cluster. Beautiful for presentations and dense images.

Harmony overlays

Harmony overlays divide the vectorscope into zones based on color theory relationships. Rotate the overlay to align zones with your image’s dominant colors and see how well your grade fits a given color scheme.

Scheme Zones Description
Complementary2Two zones opposite each other (180° apart)
Split Comp.3Base zone plus two flanking the opposite side
Triadic3Three zones equally spaced at 120°
Tetradic4Four zones in a square at 90° intervals
Analogous3Three adjacent zones clustered together
