Mac utilities

The menu bar item opens quick access to the color picker, Color Scope, Rulers, Point Measurements, and the main Huebook window. The color picker samples a pixel from another app. On supported Macs, hold Shift for the precision loupe; if screen capture access is unavailable, Huebook uses the macOS system picker. The iPhone and iPad picker uses the camera or a photo.

Huebook HUD is a floating window for quick color picking and palette work while another app stays in front. Its Color tab picks or enters one color; its Palette tab lets you build a strip, lock colors, and save it.

Color Scope magnifies an area behind its window, can simulate color-vision differences, and can analyze detected text contrast. Freeze pauses the captured image; From Image sends the current scope crop to the image palette tool. Screen capture access is needed for these live screen views. Color Scope’s contrast and simulation features have separate free trial allowances; Huebook Pro unlocks continued use.

Rulers place floating measurement scales over your screen. Add, resize, rotate, hide, or remove rulers. Point Measurements records distances between two screen points and can show a magnified loupe while placing or moving points. Physical units require calibrating each display; points and pixels are available without calibration. Point Measurements has a ten-launch free allowance, then requires Huebook Pro. These utilities are Mac-only.

Ruler gestures

Drag a ruler to move it. Drag an end cap to resize it; hold Shift for precision or Control to snap to tick lines. Hold Option while dragging to rotate, and add Shift to snap to 45°. Double-click to rotate by 90°. Closing the manager keeps visible rulers on screen. Choose the ruler and measurement color in the manager; Reset Color restores the default.

Moving measurement points

Drag a point marker to reposition it. The magnifying loupe follows while placing or moving points; hold Shift for precision.
