1. Description
The equipment set is used for demonstrating
additive and subtractive colour mixing on an
overhead projector.
It consists of a base plate with three mir-
ror/lens holders. The base plate is mounted
onto the projection surface of the overhead
projector. Depending on the projection dis-
tance, three large circles (30-80 cm in di-
ameter) are projected onto a screen or wall.
By rotating the holders and mirrors, the col-
our circles may be projected either distinctly
or partially overlapping one another.
