Generate three colours spaced equally around the HSL hue circle.
The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.
Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.
The base RGB colour becomes HSL, hues 0°, 120°, and 240° apart are generated, and each is converted back to RGB and hex. Saturation and lightness remain shared.
#FF0000
#FF0000 #00FF00 #0000FF
Posters create accents, dashboards generate categories, and colour theory exercises demonstrate hue-wheel spacing.
