What controls the border colour of the Select component?

[mitya33]

In the theme designer, the Select component doesn't have a variable to control its border colour. What does it read from, i.e. what should I set to affect it?

Thanks in advance.

Could you be more specific? That's a link talking about customising the theme in general.
