Final answer:
The student's inquiry touches on the techniques used in Op Art, where artists like Joel Sharpio use geometric patterns, patterns and parallel colored lines, and meticulous grid methods to create optical illusions that manifest as vibrant, dimensional images.
Step-by-step explanation:
The work of Joel Sharpio, which features an orange blocked human figure, is designed to play on our visual perceptions, specifically our ability to experience optical illusions. Op Art, short for Optical Art, is renowned for its use of illusions and optical effects using lines, shapes, and repetitive colors to create images that appear to have dimension or movement. This technique can cause viewers to see vibrant effects or forms emerging from the background, as seen in Vega-gyongly-2 (1.2.9) which uses circles and squares in various sizes and bright colors.
Another method associated with Op Art is the use of patterns and parallel colored lines to form illusionary images that play on perceptive ambiguity. This is exemplified in the work of Anuszkiewicz where colored lines and geometric patterns work together to give the illusion of a curved surface in pieces like Orange, Rose, Magenta Knot (6.7.12).
It’s not only about patterns and color relationships—the scale of detail matters too. Artists, such as Close, utilized grid techniques and color placement to create images that metamorphose when viewed from different distances. Elements of their techniques are comparable to the intricate design of Byzantine mosaics and highlight the necessity of minimum dots to establish a recognizable portrait.
