This document discusses optical illusions and Op Art. It provides facts about Op Art, including that Op artists used geometric designs and tessellations to create feelings of movement through their art. A key figure in the development of Op Art was Victor Vasarely, who created tessellations and works with shocking perspectives. While Op Art grew popular in the 1960s, exemplified by the major 1965 exhibit "The Responsive Eye," it never became as widespread a modern art movement as Pop Art. The primary goal of Op Art was to trick the eye through use of color and geometric patterns. Students are tasked with recreating optical illusions using color to change the visual impact.

10. Colour optical illusion
Objectives
To understand how colour can change
the visual impact of a piece of work.
Outcomes
A coloured optical illusion

11. What impact has the use of colour
had on these Op-art pieces by
Bridget Riley?

12. Which do you think
is more effective the
coloured illusions or
the monochrome
illusions?

13. Task 1
Copy the illusion on
the sheet you have
been given, but this
time use colour to
create a different
effect on your design.
For example using complimentary colours
together. Fill an A4 page.

14. Complimentary colours
Use of these
colour
combinations. This
can increase the
visual impact of
your work. These
colours make each
other seem
brighter and make
each other stand
out more boldly.

15. Home work
Copy one of the monochrome illusions in
your book and use colour to change the
effect. Briefly describe the difference
between the two designs and explain
which one you prefer and why.
