Apparently, `a_colormap(1)` outputs the wrong result. The color it produces is indistinguishable from `a_colormap(0)`, although it is slightly different. `a_colormap(1.0)` produces the correct result, but `a_colormap(1.0) != a_colormap(1)`.\r\n\r\nWhat is going on? It would be useful to clarify this in the [docs](https://matplotlib.org/stable/users/explain/colors/colormapnorms.html).\r\n\r\n**Example**\r\n```python\r\nfrom matplotlib import colors, colormaps\r\nimport matplotlib.pyplot as plt\r\n\r\nprint(colors.to_hex(colormaps[\"binary\"](0)), colors.to_hex(colormaps[\"binary\"](1.0)))\r\nprint(colors.to_hex(colormaps[\"binary\"](0)), colors.to_hex(colormaps[\"binary\"](1)))\r\n```\r\n\r\n**Output**\r\n```\r\n#ffffff #000000\r\n#ffffff #fefefe\r\n```\r\n\r\n### Proposed fix\r\n\r\nImproved documentation, or added consistency to make integer values work for the upper endpoint.","author":{"url":"https://github.com/aaronshenhao","@type":"Person","name":"aaronshenhao"},"datePublished":"2024-05-09T13:09:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":14},"url":"https://github.com/28198/matplotlib/issues/28198"}
