Chalk

Chalk draws soft, textured lines with porous edges. Press C to quickly access this tool.

 

The tool's parameters will be shown in a floating box over an image (by right-clicking the mouse) and also in the Settings Panel.

To change a parameter's setting, enter a numerical value in that parameter's box and press Enter (Mac: Return) or move the slider.

The chalk's color is set in the Color/Swatches palettes. To choose a different color bring the cursor over the spectral bar (the cursor will take the shape of a pipette) and click on the desired color or double-click on the square and choose a color from the Select Color dialog. In some cases, selecting a color is more convenient than manually selecting the components of a color via the sliders.
