I can't draw lines
If you cannot draw lines, your drawing color may be white or transparent or you may have selected a tool that cannot draw, such as the eraser.
Check the following in order.
When you can't draw anything
Check the drawing color
The white or the transparent color may be selected.
Check that a color other than white or transparent is selected from the bottom of the tool palette and then try drawing.
Note: If you double click or double tap the icon, you can select a drawing color.
Check the selected tool
When a non-drawing tool such as the eraser is selected, lines cannot be drawn.
Select the pen or pencil from the tool palette.
Check selection area
If a selection area has been created, drawing is not possible outside of it.
Click the Select menu > Deselect and clear the selection area, and then try drawing.
Check the display magnification
If a thin line is drawn when Zoom In/Out is low, the line may not be visible.
Set Zoom In/Out to 100% by selecting the View menu > 100% and check to see if the line has been drawn.
■ PCs and tablets
On PCs and tablets, you can also change the magnification by using the Zoom bar.

If you cannot draw the desired line with normal pen pressure, see here to adjust pen pressure sensitivity.
Check the expression color of the layer
If you cannot draw a line when selecting a light color such as light blue, the layer expression color may be set to Monochrome.
A monochrome layer can only be drawn in black or white.
Darker colors will be rendered as black, and lighter colors as white.
When drawing with a light color, set the layer expression color to Color via Layer Property.
■ PCs and tablets
■ Smartphones
If you intend to create a colored work, setting the Basic expression color to Color when creating the canvas will ensure that any layers created will also have their color expression set to Color.
Check layer order
If there’s a layer above the selected layer, lines can be hidden by the image in the layer above it.
Move the selected layer to the top of the layer palette and draw.
