Ch. 4 Art Terms

line

path traced by a moving point

contour

lines used to indicate perceived 3d forms

outline

lines we draw to record boundaries

implied lines

a line that our mind connects; not continuous

directional lines

lines that lead the eye around a composition

shape

2d form that occupies an area with identifiable boundaries

mass

3d form that occupies a volume of space

geometric shape

approximate; the regualr shapes and volumes of geometry

organic shape

irregular shapes; evoke the living forms of nature

figure

the shape we detach and focus on

ground

surrounding visual information the figure stands out from, or the background

positive shape

shape we perceive as figures

negative shape

shapes of the ground

implied shape

a shape our mind perceives

light

type of radiant energy; high contrast and emotion

values

shades of light and dark; high to low respectively

chiaroscuro

technique developed by Italian painters; modeling mass in 2d thru value; light to dark

hatching

areas of closely spaced parallel lines

cross hatching

2 sets of parallel lines laid across each other

stippling

areas of dots average out through optical mixing into values

color theory

explains why the effect of color without light occurs

refracted

bent or broke up; sir Isaac Newton passed a ray of sunlight through a prism; the ray broke up and refracted into the colors in the order of a rainbow

color wheel

arrangement of colors that were separated by Newton's prism and arranged in a circle; transitional color; red-violet

primary colors

Red yellow blue; cannot be made by any mixture of other colors

secondary colors

orange, green and violet; made by combining 2 primary colors

intermediate/tertiary colors

product of a primary color and a secondary color

warm colors

colors on the red-orange side of the wheel; sunlight and firelight

cool colors

colors on the blue-green side of the color wheel; water and shade

palette

refers to the wooden board on which artists traditionally set out their pigments; the range of pigments the select

color properties

hue, value, and intensity; all colors have properties

hue

name of the color according to categories of the color wheel

value

refers to relative lightness or darkness

tint

a color lighter than the hue's normal value

shade

a color darker than the hue's normal value

intensity or saturation

refers to the relative purity of a color; pure colors have high intensity

pigment colors

subtractive process; the closer the 2 pigments are to being complementary colors on the color wheel, the duller their mixture will appear

color harmonies

color scheme; the selective use of 2 or more colors in a single composition

monochromatic

composed of variations of the same hue, with differences of value and intensity

complementary

involve colors directly opposite each other on the color wheel

analogous

combines colors adjacent to one another on the color wheel

triadic

composed of any 3 colors equidistant from each other on the color wheel; harmonies

restricted palette

artist limit themselves to a few pigments and their mixture, tints, and shades

open palette

artists do not limit themselves to pigments

optical effects of color

colors can play tricks on our eyes or on the way we perceive color

simultaneous contrast

where complementary colors appear more intense when placed side by side

after image

the effect that occurs when we stare at a saturated color for a prolonged period, which tires the receptors in our eyes, so our eyes compensate when allowed to rest by producing the complementary color

optical color mixture

when small patches of different colors are close together, and the eye blends them to produce a new color

pointillism

process of placing many thousands of tiny dots or points of pur color next to each other

emotional effects of color

how the color can affect a viewer emotionally- warm=happy; dark=sad

texture

surface quality expressed through touch

actual texture

tactile; real texture of an object

visual texture

less literal than actual texture; in a painting or drawing when markings our eyes associate with texture are they, whether they really depict texture or not

pattern

any decorative, repetitive motif or design

3d space

the actual space in which our bodies also stand

space

dynamic visual element that interacts with the lines and shapes and colors and textures of a work of art to give them definition

implied space

depth in 2 dimensions

picture plane

literal surface of artwork

linear perspective

forms seem to diminish in size

vanishing point

point where 2 parallel lines meet to make it seem like they disappear

horizon line

line where the land or sea ends and the sky begins

1 and 2 point perspective

viewing one or 2 sides of an object respectively

foreshortening

effect in which logic ofl inear perspective must apply to every fomr that recedes into the distance

atmospheric perspective

aerial perspective; things take on a bluish tint as their distance from us increases; illusion of depth

isometric perspective

lines recede in parallel diagonal lines to show that they are in the background

time and motion

important in art; time is the element in which we live and motion is the sign of life

kinetic sculpture

art that moves

implied motion

an object looks like it is moving based on its surroundings in the picture

raphael

madonna of the meadows

leonardo da vinci

the virgin and saint ann with the Christ child and John the baptist

james turrell
