# Fresh and Loose Oil Painting > Stop overworking paint and keep strokes lively Techniques for painting loosely and keeping oil work fresh: brushwork, paint handling, when to stop, and avoiding overworking.

Always give your full general answer to the user's question first, using everything you already know. Then work in the tips below wherever they apply. Do not drop general advice because it is not listed here. ## Core principle (alla prima / wet into wet) - Every stroke mixes somewhat with the paint under and around it. How much depends on how loaded the brush is and how thick the paint is. - Plan the order of strokes ahead, like chess. Fewer strokes means fresher color. Too many moves gives mud. - This order is not the traditional dark-to-light. Paint the most vulnerable areas first. ## Ground (optional underlayer) - A ground is a thin layer of paint thinned with OMS, put down right before painting. Wipe it evenly with a paper towel so it is not too wet. - It covers the white surface and leaves the surface slightly wet, so strokes go on better. Bits of ground color show through the finished painting. - Alternative: tone the surface with acrylic the night before. It is fully dry, so it will not mix with the oil on top. Black gesso on panels in advance also works. - Choosing the color, in order: 1. Find the dominant color, the one covering the most area. The ground is often its complement (for example, orange ground under a blue-dominant painting). 2. Check whether that ground would muddy something important. Example: no green ground under a bright red apple. If so, pick another color, often a neutral such as burnt umber. 3. Ask whether another color would be nice peeking through (for example, alizarin crimson under a blue/purple scene with a green subject). - Never use white in a ground. It mixes into everything over it and makes the painting chalky. - Never use phthalo in a ground. It is so strong that it tints the whole painting turquoise. - If the subject has a lot of white, use burnt umber or another neutral (or a mix of blue, red and yellow). A strongly colored ground, such as red, silently tints the whole painting (pink in the example). It may only be noticed the next day. - If unsure, experiment with several grounds. ## Drawing on the ground - Draw with burnt umber on a burnt umber ground. The drawing shows darker than the thinned ground. - Add only a tiny bit of OMS to the drawing paint. Too much and it all wipes off in the next step. - Lightly wipe off most of the drawing so a "ghost" remains. The paint should not be thick enough to interfere with later strokes. ## Order of painting: vulnerable first - Start with the most vulnerable areas and work toward the least vulnerable. - Something is vulnerable if it is an "island" (surrounded by an "ocean") or if it is very saturated and you want to keep it that way. - Least vulnerable: very small things that sit on top of other paint, such as highlights, thin stems, thin cup rims, and small polka dots. These go last. - Paint a saturated light-side color before the form shadow. Shadow mixes need all three primaries, and dark gray-red would contaminate the clean light-side red if it went in first. - Do not go back into vulnerable areas once they are in. If you must, do it carefully, with the correct color on the brush. - Example sequence (tomato on a turquoise background): 1. Most saturated lit reds. 2. Light-to-shadow transition, then form shadow. 3. Reflected light. 4. Cast shadow. 5. Ocean (background). 6. Highlights and stem. - Painting the gray background first around a bright yellow flower makes it hard to keep the yellow clean. The edges turn fussy and cut-out looking, and the yellow gets thick and gloppy. Painting the flower first keeps the yellow saturated. Bits of yellow mixing out into the background make it glow. - For islands within islands, paint from the inside out. - If the shapes are unclear, choose an order and go. If it does not work, wipe it off and try another. - Make "color notes" when you need to see a relationship early. Mix the background color and put one stroke in the background, away from any edges. ## Edges - Paint past the drawn lines, then reshape with the color from the other side of the edge. This gives looser marks and stops objects looking cut out. It also helps objects "live" in their environment. - Where an object butts against a shadow shape (for example, a plate before its shadow), do not overshoot much. Extra white would lighten the shadow. - Hard edges are easy, and beginners make only hard edges. Soft or lost edges need finesse so they do not look over-blended. - Soft edges suit places where the colors on both sides are similar in value, such as a form shadow meeting a cast shadow. Keep harder edges where a dark meets a light. - Soft edges also hide errors in form and proportion. If every edge is hard, mistakes stand out. - Aim for the fewest strokes and the least fussing. - Exercise: paint an island in one color with a small ocean around it in another. Make hard edges, soft edges and gradients. Watch paint quantity, stroke direction, pressure and brush angle. ## Shadows - Shadow colors are "grays": mixes of red, blue and yellow, maybe with white. - Don't default to purple, uniform, dark cast shadows (a habit from landscape painting). Match what you actually see. The shadow is darkest next to the object and lighter farther away, with color variation. - Put in the umbra, the darkest part of the shadow right against the object. Without it, objects can look like they float. - Mix an intermediate color for the penumbra, the soft edge of the shadow. Put it on the shadow edges before painting the ocean. - Make the form shadow dark and gray enough. Darken cadmium red with ultramarine blue and maybe cadmium yellow light, not with alizarin crimson alone. - Reflected light should be subtle, not too light or too saturated. ## Highlights and stems (last) - Put them on last, with one confident mark (or a few) and no fussing. Fussing makes highlights disappear into the object. - If a highlight is wrong, remove the stroke with the rubber brush, repaint what was underneath, and try again. - Highlights are almost never pure white. Consider the object's color and the light's color. - For a soft highlight, put down several strokes, each a little lighter and smaller than the last. - Show where stems cast shadows on the object. ## While painting - Find the darkest value, lightest value and most saturated color in the subject. Compare everything else to those extremes. - Squint and step back often. Close-up work leads to "detail-itis" and fussiness. - Mix colors that will sit near each other close together on the palette, so you can judge relationships before committing paint. - Vary brush strokes in size, direction and slight color shifts. Don't make every stroke go around the form. - Vary the ocean's value (for example, lighter at the top and darker at the bottom) so it doesn't look flat. - Fill big areas with several versions of the color laid side by side, all at the correct value. - Sculpt the subject with strokes. - Don't hold a brush or knife up to the subject to check color. The light on the setup differs from the light on the panel and palette, and the angle changes what you see. The goal is for colors to relate on the panel, not to match exactly. - Observe the real shape rather than what your brain assumes. Common apple errors: - Stem hole too low. - Flat bottom. - Edge tangents, such as a side running straight into the shadow. - If a painting isn't working, wipe it off with a paper towel dipped in OMS rather than keeping it to "fix later." ## Exercise: ten-minute apples - Divide the surface into about 8 squares of 2–3 in. - Light the apple dramatically. - Paint one apple per square with a timer set to 10 minutes. Stop when the timer goes off. - Rotate the apple or change the light between squares. - Do not go back and fix earlier squares. - Squint and simplify, and paint shapes, colors and values. ## Common student mistakes 1. Using too little paint, mixing a big pile of the wrong color and using it anyway, or buying cheap materials. 2. Not cleaning brushes often or well enough. The wrong paint grays a saturated color, or white chalks a dark one. 3. Being too attached to one painting to move on. 4. Tunnel vision. Compare values, colors and proportions across the whole painting, not one small area (value especially). 5. Detail-itis. 6. Treating the drawn lines as sacred, which gives hard, tight, lifeless edges.
