Quickly and frequently adjust saturation(S) and brightness(V) using this gesture.

Tap and hold the active color icon in the brush panel, then drag up, down, left, or right to adjust the current color's saturation and brightness. Drag left or right to adjust saturation and up or down to adjust brightness. This gesture is useful for making subtle color changes while drawing.

Tap Brush Slider to Use Numpad

Accuracy matters, not just quick adjustments.

Tap the brush size slider or opacity slider once to expand them. Use them for more precise adjustments. The numpad for direct input will appear below the expanded slider. You can open or close the numpad by pressing the numbers below the expanded slider. Brush size ranges from 1mm to 300mm, and opacity ranges from 0% to 100%.

Tap Pressure Sensitivity

Adjust the intensity of the brush for more diverse expressions.

Tap to toggle pressure sensitivity on or off. When pressure sensitivity is enabled, the size, opacity, or color of the brush adjusts based on the pressure applied with the pen.

Injector

The injector is similar to the eyedropper but more advanced. It allows you to sample all properties used on a previously drawn curve, including brush type, color, size, and opacity.

Tap Injector in Brush Panel

Tap the Injector icon at the bottom of the brush panel. The icon turns black, indicating it’s ready for use. Tap again to cancel.

Drag Cruves to Sample Brush

While using the injector, select or drag the pen over the curve you want to sample. This samples the brush type, color, size, and opacity of that curve. If you only want to sample the color from a curve or imported image, use the Eyedropper.
