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.

Note: The Select > Same > Fill Color, Stroke Color, and Stroke Weight commands work within a Live Paint group when you select a face or edge with the Live Paint Selection tool; other Select > Same commands do not work. You cannot select same objects both inside and outside a Live Paint group at the same time.

To select objects with the same fill and stroke, select one of the objects, click the Select Similar Objects button in the Control panel and choose what you want to base your selection on in the menu that appears.
To select all objects with the same fill or stroke color, select an object with that fill or stroke color, or choose the color from the Color panel or Swatches panel. Then choose Select > Same and click Fill Color, Stroke Color, or Fill & Stroke on the submenu.
To select all objects with the same stroke weight, select an object with that stroke weight or choose the stroke weight from the Stroke panel. Then choose Select > Same > Stroke Weight.
To apply the same selection options using a different object (for example, if you have already selected all red objects using the Select > Same > Fill Color command and now you want to search for all green objects), select a new object and then choose Select > Reselect.
To consider the tint of an object when selecting based on color, choose Edit > Preferences > General (Windows) or Illustrator > Preferences > General (Mac OS), and then choose Select Same Tint %. With this option selected, if you select an object filled with a 50% tint of PANTONE Yellow C and choose Select > Same > Fill Color, Illustrator selects only those objects filled with a 50% tint of that color. With this option deselected, objects with any tint of PANTONE Yellow C are selected.
