For a sea-themed mural or an ocean project, you might wish to paint convincing underwater bubbles. These help add a touch of dimension, texture and charm to any water-related piece. Fortunately, you don't need professional training to paint perfect underwater bubbles.
Paint an underwater background using blue and green paint. Adding white to each color will help create several shades of the water. Leave some white space in the background for painting the bubbles.
Dip a thin paintbrush into blue or green paint that has not been mixed with white paint. Then make tiny circles in the white space of the underwater background to form the outline of the bubbles.
Use a clean, thin paintbrush of the same size to smudge out the blue circles by dipping the brush into water and going over the blue circle outlines. This gives the bubbles a soft edge. If the bubbles become indistinct after smudging with water, paint over the circle again using the original color.
Add a dot of white paint to the center of the bubbles to emulate the way they reflect light. You can make them as large or as small as you'd like, according to the nature of your water project.
