Color Harmony 1.3.0 panel: base color #E0567A, chosen color #56E0BC and the Tetradic harmony on the color wheel

Watch the panel at work.

Follow the foreground color, open a harmony, set a color, copy its value, save the palette.

Real plugin interface. Photoshop is simulated in this video.

The wheel shows the harmony.

Choose a harmony above the wheel and the points move at once. Each point sits at the real hue angle of its color, with its HEX value below the wheel. Click a point to set it in Photoshop.

Same base color #E0567A in all three. Interface rendered from the plugin 1.3.0 code, not a Photoshop screenshot.

Simulation: Photoshop runs in your browser

Try the demo.

The panel on the left runs the plugin's own interface code. Photoshop is simulated here, so pick a color below the way the Eyedropper would.

Simulated foreground color

Click any field in the panel: the plugin makes the same call it makes in Photoshop, and the simulated foreground color changes.

Made for long sessions in a dark workspace.
