This article deals with the way colours in a room
affect each other through contrast effects and reflections.
The study presented is based on the visual observations of
the colour appearance of three inherent colours in a sequence
of experimental situations. My point of departure
was a yellow, blue, and red room. The room had distinctly
different colour appearances of the same inherent colours
when observed at different locations. The effects of both
contrasts and reflections were evident. However, reflection
effects seemed to dominate the situation. In a study of small
experimental rooms, different combinations of the same
three inherent colours were systematically tested. Comparisons
were made to examine the differences in colour appearance
between monochromatic rooms and multicoloured
rooms with varying colour schemes. The illumination was
kept stable. In the cases studied, it was obvious how the
colours in the two-coloured rooms became more alike or
“neutralized each other.” The contrast strengthening between
abutting areas on the same level had distinct significance
for colour appearance and perception of space.
However, not in such a way that the perceived colour
differences became larger in the two-coloured room than
between each monochromatic rooms
