Randomizing color

Jump to Mobile

Quickly lay down varying colored strokes using the same brush. I’ve found this really fun to use when playing with Radial Symmetry. Set a range for the hue, saturation, and luminance of the active color.

    Randomize color in the Sketchbook Color Editor

  3. Select the color range you want to randomize from the dropdown 
  • HSL – use the sliders to define the hue, saturation and lightness ranges you want the randomized colors to fall within. Blue indicators over the color wheel will preview the range
  • Palette – colors will be chosen at random from the currently selected palette in the Custom Colors window. The Custom Colors‍ window does not need to be open for this selection to be enabled, however you might want to open it to double-check which palette is currently selected.
  • Gradient – colors will be chosen from the gradient (including Color History) pinned to the Color Editor.

When Randomize is on, if you have the Color Puck‍ visible you will see the randomize icon in the center of the puck.

To turn off Randomize Color, tap one of the other color selection options: HSL, HSV, RGB, or Gradient
