American Labor Market
58 years of U.S. employment data on a single slider. Watch how each sector's share of the workforce compares to its share of job creation — from 1968 to 2025. Includes unemployment, S&P 500, Fed rate, and workforce demographics.
ExploreWhat's My ΔE?
Test how finely your eyes can distinguish color. Two colors appear side by side — click where they meet. Each round the difference shrinks until we find your Just Noticeable Difference, measured in CIEDE2000.
PlayOdd One Out
A 3×3 grid of color swatches. Eight are the same — one is different. Click the odd one out. No shared edges, no tricks — just your eyes against increasingly subtle CIEDE2000 differences.
PlayPurple Haze
Why does blue go purple when you fade it to black? Pick any color and watch it interpolate to white and black across nine color spaces side by side — sRGB, HSL, CIE L*a*b*, OKLab, and more. See the hue shifts for yourself.
LaunchInterpolation Paths
See how color interpolation actually moves through 3D CIELAB space. Pick a color and a tween space, then watch the path from that color to white and black — rendered as curves through the visible gamut.
LaunchGamut Viewer
Explore a 3D model of every color the human eye can see. Switch between CIELAB and CIE xyY coordinate spaces, overlay sRGB, Adobe RGB, and Display P3 gamut boundaries, and discover how much of visible color your screen can actually show.
