Joe Garcia in The Watercolor Bible puts it well when he says “A common misconception about watercolor is that it’s one of the most difficult mediums to use because you cannot correct mistakes.” In fact, you CAN often correct or adjust mistakes in watercolor painting! You can lift colors, blot, scrub, scrape, change values by lifting or glazing, even adjust a composition.
One of the simplest techniques to correct a mistake involves BLOTTING AND LIFTING wet paint. If while you’re painting you accidentally smudge or paint over an area you intended to keep white, quickly blot up the wet paint with a paper towel or tissue. As long as you have not painted with a staining pigment, the color will lift.
(Suggestion: Become aware of which paints on your palette are considered staining. Common staining colors that cannot be easily lifted include Permanent Alizarin Crimson, Phthalo Blue, Phthalo Green, some of the Sap Greens, Gamboge, Permanent Rose, Prussian Blue.)
Another technique used to alter wet paint is using a THIRSTY BRUSH to remove some color from your painting, e.g., to lighten a wash, create a highlight, or lift out clouds. The painted surface should be damp, with the shine just about to go dull. A ‘thirsty’ brush has been moistened but squeezed nearly dry before the brush is moved over the moist painted surface. After each lifting stroke with a thirsty brush, wipe the brush clean to remove wetness and lifted paint from the brush, before continuing to lift.
If your paint has dried, WETTING AND LIFTING can remove areas of dark color. A staining color will require a stiffer brush and stronger scrubbing to lift any color. Use a very wet brush to wet the area where paint will be lifted.
Work in small areas to loosen and lift paint, before moving and moistening a new spot. SCRUB until the water loosens the dried pigment. Quickly blot to absorb the liquid with a paper towel or tissue, removing the loosened pigment along with the water. Do not let the loosened color remain on the scrubbed surface. It can be reabsorbed by the damaged paper fibers and not be able to be lifted again. Be sure to have a wet enough brush when using this technique – using just a damp brush may rough up the paper and scrub the paint deeper into the paper. A slight variation to the above scrub and blot technique would be WIPING OFF COLOR with a paper towel or tissue.

SCRAPING can help you recover a lost highlight or create sparkle. You can scrape with a variety of tools (for different effects), either before your applied paint dries or after. Create tree trunks; for example, scrape wet paint with a palette knife or hard brush handle. Scraping can form dark marks on wet paint as the paint flows into the scrape. Or, on less wet but still damp paint, scrape in lighter marks as paint is pushed away from the scraping.

Rocks can be highlighted and textured with a knife or palette knife by scraping and pushing damp paint. An X-acto knife can scrape dried paint to reclaim highlights, generate sparkle on water, or repair unsuccessful dry brush work. Keep in mind that scraping can damage paper, so it should be one of the last adjustments made to your painting. (Sandpaper can also remove pigment and bring back the white of the paper, although it also damages the paper.)
Hazel Soan, in The Essence of Watercolour, maintains that errors in “light-toned early washes are NOT a problem. As soon as darker tones are employed the eye is distracted from the pale tones.” Soan goes on to suggest that sometimes you can reclaim your watercolor by disguising or DISTRACTING from a mistake. Add a dark-toned accent nearby the error, such as some grasses or reeds, “to distract the eye away from the problem.”
OPAQUE colors, if not overdone, can be used to cover some painting mistakes or recreate lost highlights. Edges can be redrawn with an opaque color. Titanium White, full strength, can hide a mistake against white paper, while a matching opaque color can reclaim a colored background.
Too many layers of paint will eventually destroy transparency. So, to preserve transparency, consider GLAZING to improve color harmony. Tame overly bright colors, make shadows interesting, or even enliven dull dark color by glazing with a TRANSPARENT pigment. When glazing, make sure the surface of the paper is thoroughly dry. To calm bright colors, choose a transparent NON-STAINING pigment and apply quickly (without scrubbing). To rescue dull, dark colors, use transparent STAINING pigments (such as Permanent Alizarin Crimson, Phthalo Blue, or Phthalo Green) for glazing. As Jean Dobie explains in Making Color Sing, “turn an error into an asset!”

By accentuating some areas of your painting and playing down other sections, perhaps by glazing or lifting, you can improve your focal point or center of interest. If a picture lacks a strong focal point or the center of interest is too weak, increase contrast of lights and darks between your focal point and the background. If your center of interest is too broad, choose a smaller area, strengthen color and contrast here, then darken or soften the surrounding sections to make the focal point stand out.
Try not to rush to correct all your painting mistakes. It is sometimes best to evaluate your work near the end of the painting process when you can see how one area affects or supports the other sections of a picture. While many mistakes can be corrected or improved, at times it can be best to start a picture over. Try to learn from any blunder. With experience you will become confident about what you can correct as well as knowing when you probably should begin anew. Don’t get discouraged – becoming frustrated or giving up could be the worst mistakes of all.
