Recommendation of color scale in Plotly

I have to admit that when it comes to change the colorscale of a graph, it’s the most frustrating time. Since every graph has different ways of changing it, go and px have different ways of changing it. the figure reference library is not very clear, it did’t state which functions to write, at least I don’t understand it very well. If there can be a detailed guide of how to change color under each circumstance, that will be very helpful.
It’s not a complaint, I know everyone is working hard to solve problems that are priorities, just a recommendation for the future.
Grateful.
