Color schema for conditions in automations

Hello, I don’t know if it was already asked, but is it possible to add some css to do a better visual separation of the options: “choose”, “and & or” inside of automations?
Because often the automations are more readable in yaml then in html
I think that a schema of 4-5 colors should be ok to do the job, please see the screenshot I am attaching (ok the colors I’ve choose sucks but it is just to let you better figure out what I am saying)
