30 Painting Techniques trivia questions
Q1. What are the three primary colors in traditional (pigment-based) color mixing?
Answer: Red, yellow, and blue
💡 RGB (red, green, blue) are the primary colors of light (additive color). CMYK (cyan, magenta, yellow, black) are the primaries for print. RYB (red, yellow, blue) is the traditional artist's model.
Q2. Which classic folding easel design packs its own palette and paints inside a hinged wooden box?
Answer: French easel
💡 French easels are heavy and slow to set up compared to today's lighter pochade boxes, but many plein air painters still swear by them.
Q3. Which of these painting surfaces visibly flexes when you press a finger against it?
Answer: Stretched canvas
💡 That give is exactly why rigid panels resist the kind of cracking that can eventually appear on old, flexing canvases.
Q4. Which brush shape tapers to a fine point, good for both fills and detail lines?
Answer: Round brush
💡 Tiny round brushes (sizes 0-4) are the go-to for signatures and fine facial details.
Q5. Which soft, splayed-bristle brush blends paint and softens foliage texture?
Answer: Fan brush
💡 Fan brushes are also dragged lightly over dry paint to fake grass or hair strands.
Q6. What is the 'wet-on-wet' watercolor technique?
Answer: Applying wet paint to paper that's already wet, creating soft, diffused edges
💡 Wet-on-wet creates unpredictable, beautiful blooms and gradients. To slow drying for longer working time, use a spray bottle and work on dampened watercolor paper.
Q7. What distinguishes 'gouache' from standard watercolor?
Answer: Gouache is opaque (covers previous layers); watercolor is transparent
💡 Gouache's opacity makes it ideal for graphic design, illustration, and adding white highlights on dark paper. It can be rewetted like watercolor but tends to crack if applied too thickly.
Q8. In oil painting, what does 'fat over lean' mean?
Answer: Each successive paint layer should have more oil than the previous to ensure proper drying
💡 Oil-rich layers dry more slowly and flexibly. If a lean layer is applied over a fat one, the fast-drying lean layer can crack as the slower fat layer below still moves during drying.
Q9. What does 'gesso' do when applied to a canvas?
Answer: Primes and seals the surface, providing tooth for paint to adhere to
💡 Traditional gesso (chalk + rabbit skin glue) was for oil on wooden panels. Modern acrylic gesso works on canvas and is far less brittle. It's usually white but clear and black gesso also exist.
Q10. What are 'complementary colors'?
Answer: Colors opposite each other on the color wheel
💡 Red/green, blue/orange, yellow/purple are the main pairs. Side by side they vibrate visually; mixed together they neutralize to grey/brown.
Q11. What is 'hot press' watercolor paper?
Answer: Smooth, hard-surfaced paper ideal for detailed work and clean edges
💡 Hot press paper is made by pressing wet paper through heated metal rollers, compressing the fibers to a smooth surface. It's popular for illustration, botanical art, and pen-and-ink work.
Q12. Why is 'cotton rag' paper preferred in fine art?
Answer: It's acid-free, archival, and stronger when wet
💡 Cotton rag paper is made from cotton fibers — the same material as currency. Unlike wood pulp, which contains lignin that causes yellowing, cotton paper lasts centuries.
Q13. What is 'cold wax medium' in painting?
Answer: A beeswax-and-solvent paste mixed with oil paint for matte texture
💡 Cold wax mixes with oil paint without heat, unlike traditional encaustic. It's used for mark-making and texture and yields subtly luminous, matte surfaces.
Q14. Which property makes some watercolor pigments nearly impossible to lift once fully dry?
Answer: Staining
💡 Staining pigments like phthalo blue are so fine they lodge inside the paper's fibers instead of sitting on top.
Q15. What do the letter-and-number codes on paint tubes, like PY35, actually identify?
Answer: The pigment's exact chemical identity
💡 PB29 always means ultramarine blue and PY35 always means cadmium yellow, no matter which brand's name is on the label.
Q16. Which oil, pressed from a thistle-like crop's seeds, keeps white oil paint from yellowing?
Answer: Safflower oil
💡 Safflower oil contains almost no linolenic acid — the fatty acid mainly responsible for linseed oil's telltale yellow tinge.
Q17. Why should a paintbrush never be stored standing bristles-down in a jar of water?
Answer: The bristles bend out of shape permanently
💡 Water can also creep past the ferrule and swell the wooden handle from the inside out.
Q18. Painting rubbery liquid onto watercolor paper, then peeling it off to reveal white paper, uses what?
Answer: Masking fluid
💡 Masking fluid is mostly liquid latex — it dries into a peelable film, but binders warn not to leave it on too long or it can bond too tightly to the paper.
Q19. Which single-word finish would you ask for to make a varnished painting completely non-reflective?
Answer: Matte
💡 Many painters brush on a gloss layer first for protection, then a final matte coat just to knock back the shine.
Q20. What's the substance that binds pigment particles into a paintable film called?
Answer: Binder
💡 Linseed oil and gum arabic are natural binders; acrylic polymer emulsion is a synthetic one.
Q21. What's the grippy texture of a canvas's weave, which helps paint adhere, called?
Answer: Tooth
💡 Coarser-tooth canvas suits heavy impasto, while fine-tooth canvas favors detailed portrait work.
Q22. What's the wooden frame called that holds canvas stretched taut for painting?
Answer: Stretcher bar
💡 Most stretcher bars have mitered slots at the corners so they can be pried apart and re-keyed.
Q23. Rubbing a little oil into dull, sunken patches of a drying oil painting is called what?
Answer: Oiling out
💡 The dulling itself is called 'sinking in' — thin, underbound paint absorbs into the layers beneath it and loses its glow.
Q24. Which acrylic medium slows drying time so colors can be blended more like oil paint?
Answer: Retarder
💡 Without a retarder, acrylic's fast evaporation-based drying can seal a blend before a painter even finishes softening the edge.
Q25. Which additive breaks acrylic paint's surface tension so it spreads and flows more smoothly?
Answer: Flow improver
💡 It's basically a wetting agent — unlike thinning with plain water, it doesn't weaken the paint's color strength.
Q26. Wiping most paint off the brush before dragging it for a scratchy, textured streak is called what?
Answer: Dry brush technique
💡 A stiff-bristled brush gives sharp, defined dry-brush lines, while a soft brush produces a lighter, dustier version of the same effect.
Q27. Flicking a loaded brush or toothbrush at a canvas to fling tiny paint droplets is called what?
Answer: Spattering
💡 Standing closer packs the droplets into a tight cluster; stepping back scatters them into a fine, misty spray.
Q28. Which oval, flat brush with rounded corners blends without harsh edges?
Answer: Filbert brush
💡 A small filbert can still cover broad areas, then flip to a pointed edge for detail work.
Q29. Which long-haired, fine-tipped brush paints ship rigging lines and thin branches?
Answer: Rigger brush
💡 A rigger holds more paint than a same-size round, letting it stroke a long line unbroken.
Q30. What's the term for a pigment that visibly fades or shifts with light exposure?
Answer: Fugitive pigment
💡 Alizarin Crimson is a famous fugitive pigment, often browning within just a few years.
