Change the themes' parameters

Select a previously created theme via the list at the top-right, and then you can change its lightness scale. By selecting another theme, the lightness scale updates and then can be adjusted with the slider.

In addition, in the Colors themes, you can change the following:

• Color theme name.

• Palette background color (can be darker for a dark mode).

• Color theme description (expand first by clicking the Ellipsis icon).

The number inputs copycat the Figma ones.
