A browser-based tool for visualizing colour data. Paste hex/RGB/HSL/HSV values or upload a CSV; colours are grouped using k-means and displayed across multiple visualization types.
- Multiple input formats — hex, RGB, HSL, HSV (one per line), or CSV upload with flexible column mapping
- K-means clustering — groups colours perceptually using LAB or HSL colour space, 2–30 clusters
- Sort options — by cluster, hue, saturation, lightness, or perceptual luminance
- Four views — Colour Strip, Colour Grid, Scatter (H×L, H×S, 3D H/S/L), and Colour Wheel
- Cluster statistics — per-cluster stats panel
- Export — PNG or CSV
- Paste colour values (one per line) or upload a CSV and map the colour column(s)
- Adjust clustering settings and click Visualize
- Switch between Strip, Grid, Scatter, and Wheel views
- Export as PNG or CSV
