Bug report

The documentation page on Colormaps has a link to vischeck.com but vischeck.com is no more available. The link is broken and should be changed.

Link to documentation page: https://matplotlib.org/users/colormaps.html

Unfortunately I do not know of any alternate websites that it can be replaced with. However, making colorblind-friendly images is very important from an accessibility point of view and this broken link should definitely be replaced.
