Painting methods
Illustrator provides two methods of painting: assigning a fill, stroke, or both to an entire object, and converting the object to a Live Paint group and assigning fills or strokes to the separate edges and faces of paths within it.
Paint an object
After you draw an object, you assign a fill, stroke, or both to it. You can then draw other objects that you can paint similarly, layering each new object on top of the previous ones. The result is something like a collage made out of shapes cut from colored paper, with the look of the artwork depending on which objects are on top in the stack of layered objects.

Paint a Live Paint group
With the Live Paint method, you paint more like you would with a traditional coloring tool, without regard to layers or stacking order, which can make for a more natural workflow. All objects in a Live Paint group are treated as if they are part of the same flat surface. This means you can draw several paths and then color separately each area enclosed by these paths (called a face). You can also assign different stroke colors and weights to portions of a path between intersections (called an edge). The result is that, much like a coloring book, you can fill each face and stroke each edge with a different color. As you move and reshape paths in a Live Paint group, the faces and edges automatically adjust in response.

About fills and strokes
A fill is a color, pattern, or gradient inside an object. You can apply fills to open and closed objects and to faces of Live Paint groups.
The current fill and stroke colors are displayed in the Tools panel.

Apply a fill color to an object
You can apply one color, pattern, or gradient to an entire object, or you can use Live Paint groups and apply different colors to different faces within the object.
Draw and merge paths with the Blob Brush tool
Use the Blob Brush tool to paint filled shapes that you can intersect and merge with other shapes of the same color.
The Blob Brush tool uses the same default brush options as calligraphic brushes. (See Calligraphic brush options.)

To see a video on using the Blob Brush tool, see www.adobe.com/go/lrvid4018_ai. To see an example of using the Blob Brush to create a complex drawing, see www.adobe.com/go/learn_ai_tutorials_blob_brush_en.

Blob Brush tool guidelines
When using the Blob Brush tool, keep the following guidelines in mind:
To merge paths, they must be adjacent in stacking order.
The Blob Brush tool creates paths with a fill and no stroke. If you want your Blob Brush paths to merge with existing artwork, make sure that the artwork has the same fill color and no stroke.
When drawing paths with the Blob Brush tool, new paths merge with the topmost matching path encountered. If the new path touches more than one matching path within the same group or layer, all of the intersecting paths are merged together.
To apply paint attributes (such as effects or transparency) to the Blob Brush tool, select the brush and set the attributes in the Appearances panel before you start drawing.
You can use the Blob Brush tool to merge paths created by other tools. To do this make sure that the existing artwork does not have a stroke; then set up the Blob Brush tool to have the same fill color, and draw a new path that intersects all of the paths that you want to merge together.
Create merged paths
Remember that paths with strokes cannot be merged.
Select the path into which you want to merge a new path.
In the Appearances panel, deselect New Art Has Basic Appearance. When this option is deselected, the Blob Brush tool uses the attributes of the selected artwork.
Select the Blob Brush tool
, and
make sure it uses the same appearances as the selected artwork.Draw paths that intersect with the artwork. If the paths don’t merge, check to make sure that the Blob Brush tool’s attributes exactly match the existing path attributes, and that neither uses a stroke.
Blob Brush tool options
Double-click the Blob Brush tool in the Tools panel and set any of the following options:
- Keep Selected
- Specifies that when you draw a merged path, all paths are selected and remain selected as you continue to draw. This option is useful for viewing all paths that are included in the merged path.
- Merge only with Selection
- Specifies that new strokes merge only with the existing selected path. If you select this option, the new stroke is not merged with another intersecting path that is not selected.
- Fidelity
- Controls how far you have to move your mouse or stylus before Illustrator adds a new anchor point to the path. For example, a Fidelity value of 2.5 means that tool movements of less than 2.5 pixels aren’t registered. Fidelity can range from 0.5 to 20 pixels; the higher the value, the smoother and less complex the path.
- Smoothness
- Controls the amount of smoothing that Illustrator applies when you use the tool. Smoothness can range from 0% to 100%; the higher the percentage, the smoother the path.
- Size
- Determines the size of the brush.
- Angle
- Determines the angle of rotation for the brush. Drag the arrowhead in the preview, or enter a value in the Angle text box.
- Roundness
- Determines roundness of the brush. Drag a black dot in the preview away from or toward the center, or enter a value in the Roundness text box. The higher the value, the greater the roundness.
Convert strokes to compound paths
Converting a stroke to a compound path lets you modify the outline of the stroke. For example, you can create a stroke with a varied width or divide the stroke into pieces.
Select objects with the same fill and stroke
You can select objects that have the same attributes, including fill color, stroke color, and stroke weight.
Create multiple fills and strokes
You use the Appearance panel to create multiple fills and strokes for the same object. Adding multiple fills and strokes to an object is the basis for creating many interesting effects. For example, you can create a second, narrower stroke on top of a wide stroke, or you can apply an effect to one fill but not the other.
Create strokes with variable widths
About the Width tool
The Width tool is available from the Tools panel. It allows you to create a variable width stroke and save the variable width as a profile that can be applied to other strokes.
When you mouse over a stroke with the Width tool, a hollow diamond appears on the path with handles. You can adjust the stroke width, move the width point, duplicate the width point, and delete the width point.
For multiple strokes, the width tool adjusts only the active stroke. If you want to adjust a stroke, make sure that you select it as the active stroke in the Appearance panel.
For a video on using the Width tool, see www.adobe.com/go/lrvid5206_ai_en.
Using the Width tool
To create or modify a width point using the Width Point Edit dialog box, double-click the stroke using the Width tool and edit the values for the width point. If you select the Adjust Adjoining Width Points option, changes to the selected width point affect neighboring width points as well.
If you press Shift and double-click the width point, then this check box is selected automatically.
The Width tool distinguishes between continuous and discontinuous width points while adjusting variable width.

To create a discontinuous width point do the following:
Create two width points on a stroke with different stroke widths.
Two points with different stroke widthDrag one width point on to the other width point to create a discontinuous width point for the stroke.
Discontinuous width point created by dragging one width point on to the other width point.
For discontinuous points, the Width Point Edit dialog box shows both sets of side widths.

The Single Width Only check boxes allow using either incoming or outgoing width leaving a single continuous width point.
Width tool controls
The following table lists the keyboard modifiers to use while working with the Width tool:
Width control tasks |
Keyboard modifiers |
|---|---|
Create non-uniform widths |
Alt+drag (Windows) or Opt+drag (Mac OS) |
Create a copy of the width point |
Alt+drag the width point (Windows) or Opt+drag the width point (Mac OS) |
Copy and move all the points along the path |
Alt+Shift+drag (Windows) or Opt+Shift+drag (Mac OS) |
Change the position of multiple width points |
Shift+drag |
Select multiple width points |
Shift+click |
Delete selected width points |
Delete |
Deselect a width point |
Esc |
You can drag the handles outward or inward to adjust the stroke width at that location on the path. Width points created at a corner or at a direct-selected anchor point, stick to the anchor point during basic editing of the path.
To change the position of the width point, drag the point along the path.
To select multiple width points, press Shift and click. The Width Point Edit dialog box is displayed, where you can specify values for Side1 and Side 2 of multiple points. Any adjustment to the width points, would impact all the selected width points.
You can also globally adjust the stroke weight for all the width points by specifying the stroke weight in the Weight drop-down list of the Stroke panel.
Saving width profiles
After defining the stroke width, you can save the variable width profile from the Stroke panel or the Control panel.

- A.
- Uniform Width Profile option
- B.
- Save Width Profile icon
- C.
- Delete Width Profile icon
- D.
- Reset Width Profile icon
Width profiles can be applied to selected paths by choosing them from the Width Profile drop-down list in the Control panel or Stroke panel. When a stroke with no variable width is selected, the list displays the Uniform option. You can also select the Uniform option to remove a variable width profile from an object.
To restore the default width profile set, click the Reset Profiles button at the bottom of the Profile drop down list.
If you apply a variable width profile to a stroke, then it is indicated with an asterisk (*) in the Appearance panel.
For Art and Pattern brushes, the Width Points/Profile option is automatically selected for size in Stroke Options dialog box after editing a brush path with the Variable Width tool or applying a Width Profile preset. To remove any width profile changes, select the Fixed option for size or one of the tablet data channels, such as Pressure, to restore the tablet data options.
For a video on creating variable width profiles, see www.adobe.com/go/lrvid5215_ai_en.
