v3: in select boxes the accent colour is used for the unselected items

[sybrenstuvel]

Select boxes have their items coloured in the accent colour. The selected item is coloured in a more dimmed, neutral colour:

In the image above, I would expect "OFF" to be the selected item, but it is actually "COOL".

What is the selected item is more obvious when there are more than two items. It remains an unconventional design choice though, especially since for toggle sliders the accent colour indicates "on" and the dimmed colour indicates "off". I would recommend giving "on" / "selected" similar colours, and the same for "off" / "unselected".
