<｜begin▁of▁sentence｜>### Instruction:
Suppose you have been working with a PrecalculatedPalette instance, which contains a list of different colors used for graph visualizations. After several operations, you want to ensure that any cached results are cleared to avoid potential issues with outdated color mappings. How would you clear the cache for the PrecalculatedPalette?
### Response:
from igraph.drawing.colors import PrecalculatedPalette

# Assuming we've been using a PrecalculatedPalette instance
palette = PrecalculatedPalette(['red', 'green', 'blue'])

# After performing some operations that caches the results
# We can clear the cache using the following command
palette.clear_cache()
