Cmap 'Blues' instead of 'Oranges'

[pierrepo]

There might be a typo in the tips & tricks handout where a Blues color map is called although an Oranges one is displayed:

For consistency, maybe we could use

cmap = plt.get_cmap("Oranges")

instead of

cmap = plt.get_cmap("Blues")

You're right, thanks. Can you make a PR (ese I can correct it directly)?

This appears to have been fixed in #24. The current (fixed) handout for tips & tricks is available at https://matplotlib.org/cheatsheets/handout-tips.pdf.
