• Provides practice projects and exercises to help students develop their oil painting skills

Key Concepts and Terms

• Pigment: colored substance, usually in powder form, used to create paints
• Binder: substance that holds pigment particles together and adheres them to the painting surface (linseed oil)
• Medium: substance added to oil paint to modify its consistency, drying time, or texture (turpentine, mineral spirits)
• Gesso: white primer applied to canvas or other painting surfaces to create a smooth, receptive surface for oil paint
• Impasto: thick application of paint, often using a palette knife, to create texture and dimensionality
• Glazing: applying thin, transparent layers of paint over dry layers to build up color and depth
• Fat over lean: principle of applying thicker, more oil-rich layers over thinner, less oil-rich layers to prevent cracking
• Chiaroscuro: strong contrast between light and dark areas in a painting, used to create drama and depth

Materials and Setup

• Paints: oil paints in a range of colors, including primary colors (red, blue, yellow), earth tones, and white
• Brushes: various sizes and shapes of brushes made with natural or synthetic bristles (flat, round, filbert)
  • Flat brushes are versatile and can be used for broad strokes or fine lines
  • Round brushes are ideal for detailed work and blending
  • Filbert brushes have a rounded tip and can be used for softening edges and creating rounded shapes
• Palette: surface for mixing colors, can be a traditional wooden palette, disposable paper palette, or glass sheet
• Palette knife: tool with a flexible metal blade used for mixing colors, applying paint, and creating texture
• Solvents: substances used to thin paint and clean brushes (turpentine, mineral spirits)
• Canvas: common painting surface made of cotton or linen fabric stretched over a wooden frame
• Easel: stand that holds the canvas upright and at a comfortable working angle

Basic Oil Painting Techniques

• Underpainting: initial layer of paint that establishes the basic composition, values, and color scheme
• Blending: softening the transition between colors or values by gradually mixing them together on the canvas
• Dry brush: using a brush with very little paint to create a scratchy, textured effect
• Scumbling: applying a thin, broken layer of opaque paint over a dry layer to create a softening effect
• Sgraffito: scratching through wet paint to reveal the layer beneath, creating a textured or patterned effect
• Palette knife painting: using a palette knife instead of a brush to apply paint, often for creating bold, textured strokes
• Wet-on-wet: applying wet paint onto a layer of still-wet paint, allowing the colors to blend and mix on the canvas

Color Theory and Mixing

• Primary colors: red, blue, and yellow; cannot be created by mixing other colors
• Secondary colors: green, orange, and purple; created by mixing two primary colors
• Tertiary colors: created by mixing a primary color with an adjacent secondary color (red-orange, yellow-green)
• Complementary colors: colors opposite each other on the color wheel (red and green, blue and orange)
  • When mixed together, complementary colors create neutral tones like gray and brown
  • When placed next to each other, complementary colors create strong contrast and visual interest
• Warm colors: colors associated with heat and energy (red, orange, yellow)
• Cool colors: colors associated with calmness and distance (blue, green, purple)
• Tint: a color mixed with white to create a lighter version
• Shade: a color mixed with black or its complement to create a darker version

Composition and Subject Matter

• Rule of thirds: dividing the canvas into thirds horizontally and vertically, and placing key elements along the lines or at the intersections
• Leading lines: lines within the composition that guide the viewer's eye towards the focal point
• Focal point: the main area of interest in the painting, often placed off-center for a more dynamic composition
• Balance: arranging elements within the composition to create a sense of equilibrium (symmetrical, asymmetrical)
• Simplification: reducing the complexity of a scene by omitting unnecessary details and focusing on essential elements
• Still life: an arrangement of inanimate objects as the subject of a painting (fruit, flowers, household items)
• Landscape: an outdoor scene featuring natural elements like mountains, trees, and bodies of water
• Portrait: a painting of a person or group of people, often focusing on the face and upper body

Famous Oil Painters and Their Styles

• Leonardo da Vinci (Mona Lisa): known for his sfumato technique, which creates soft, hazy transitions between colors and tones
• Rembrandt van Rijn (The Night Watch): master of chiaroscuro, using strong contrasts of light and shadow to create drama and depth
• Claude Monet (Water Lilies series): a pioneer of Impressionism, characterized by loose brushwork, bright colors, and an emphasis on capturing the changing effects of light
• Vincent van Gogh (The Starry Night): known for his expressive, impasto brushwork and vibrant, emotive use of color
• Frida Kahlo (The Two Fridas): known for her surrealist self-portraits that often incorporate symbolism and elements of Mexican folk art
• Georgia O'Keeffe (Black Iris): known for her large-scale, close-up paintings of flowers and natural forms, characterized by simplified shapes and smooth blending

Practice Projects and Exercises

• Monochromatic painting: create a painting using only one color and its tints and shades to practice value and composition
• Color mixing chart: create a grid of colors by mixing primary, secondary, and tertiary colors to familiarize yourself with color relationships
• Still life setup: arrange a simple still life with a few objects and a single light source, focusing on accurate color mixing and value relationships
• Landscape study: paint a small outdoor scene en plein air (on location) to practice capturing light, atmosphere, and color
• Portrait study: paint a self-portrait or a portrait of a friend or family member, focusing on proportions, skin tones, and capturing likeness
• Master study: choose a famous oil painting and create a small-scale copy to analyze and learn from the artist's techniques and style
• Experimental techniques: try out different application methods like palette knife painting, sgraffito, or impasto to explore texture and mark-making
