[Docs] When using a custom color, it jumps after a short amount of time

[Floriferous]

When you apply a custom color to the material-ui docs, it is saved for each visit.

The experience isn't really great though, because the color first shows the original blue, and jumps to the custom color after ~500ms.

It'd be nice if it would load with the proper color from the start.

We agree but it's not possible with the current documentation tradeoff. The documentation is rendered, once, on the server. It's the same output for everybody. One leverage we have used in the past to improve the situation is to have as many client-side page transition as possible (not required to load the .html of the page). The only other leverage we have is to improve the time to the interaction of the documentation. The best opportunity here is to speed up the markdown handling. Before considering this problem, I think that we should add Google Analytics custom dimensions to see how many people are impacted. My guess: it's not important enough. But improving the documentation performance might have a good ROI.
