§35

Wittgenstein grants that there may be characteristic experiences of pointing to the shape of something rather than pointing to its colour. But a characteristic-something isn't a necessary connection. A person with a certain character (e.g. friendly) isn't necessarily always friendly.
It is not the characteristic experience - if there is indeed a characteristic experience - of pointing at the colour of something that makes something an instance of pointing at the colour. This depends on the context - what happens before and after.
