The Same Color Illusion
Explanation:
Are square A and B the same color? They are. Are too.
To verify this, click on the
above image
to see them connected.
The
above illusion
, called the
same color illusion
,
illustrates that purely human observations in science may be
ambiguous
or inaccurate.
Even such a seemingly direct perception as relative color.
Similar illusions exist on the sky, such as the
size of the Moon near the horizon
,
or the
apparent shapes of astronomical objects
.
The advent of automated, reproducible, measuring devices such as
CCDs
have made science in general and astronomy in particular less prone to,
but not free of,
human-biased
illusions
.
