A person is applying sealant with a caulking gun along the edge of a kitchen countertop. The countertop is a dark, speckled material. Above it is a backsplash made of vertical tiles in alternating shades of white and beige. A strip of purple painter’s tape runs along the top edge of the countertop, just below the backsplash. The person is wearing a watch with an orange band on their left wrist. An electrical outlet is visible on the backsplash. The caulking gun is loaded with a tube of sealant that has a red, green, and white label. The lighting in the kitchen is bright, and there is a light fixture visible above the tiles. A blue tool is lying on the countertop.
