描述

There seems to be an issue with the "Reds" and "Turbo" colorscales. I couldn't find an existing issue about this, so here is how to reproduce: I just got this example from plotly page:
https://plotly.com/python/dropdowns/#update-several-data-attributes
And added the "Reds" and "Turbo" colorscales.

The "Reds" seem to work, but it is inverted when comparing to the "Blues" and "Greens":

The "Turbo", on the other hand, shows up like a "coolwarm" colorscale instead:

These two are different than the ones described on the documentation here: https://plotly.com/python/builtin-colorscales/#builtin-sequential-color-scales

I had similar issues when using "Plotly.update" with plotly.js to update the coloscales.

edit: Also the "Inferno" shows as the "coolwarm" one:

Probably there are others too.

调研方向

从链接的 Plotly Python dropdown 示例和已报告的 Plotly.update 复现开始,然后将 Reds、Turbo 和 Inferno 的结果与内置顺序色阶文档进行比较。跟踪这些色阶在哪里被选择或转换;当它们在报告的两条更新路径中都使用文档所述的调色板进行渲染时,即表示完成。
