Definitely trust you to make the best translation, but just noting that in most languages this is only the colour, e.g. “Light” or “Dark” and doesn’t also include the word “theme”, so you have the accessible “테마 선택” label followed by the theme name and it looks like for the “auto” variant, this is still the case: “자동”, even though the light and dark translations include “theme” (“테마”).

That is totally fine if the meaning here is otherwise unclear and “테마” helps to clarify it but wanted to note it.

That's a very reasonable question, and it's something I also considered carefully.

You're right that in English, 'Dark' and 'Light' are common conventions likely understood as 'Dark Theme' and 'Light Theme'.

However, in Korean, using just the adjective form – like '어두운' (eodun - meaning 'dark') or '밝은' (balgeun - meaning 'light') – as a standalone UI option often feels grammatically awkward or incomplete. It leaves the user wondering, "Dark what?". This might be a key difference compared to how adjectives function in English UI labels.

I also tried using the loanwords '다크' (Dark) and '라이트' (Light), but they similarly felt somewhat unnatural or abrupt when used alone in this context.

Therefore, to ensure the meaning is absolutely clear and feels natural to Korean users, I decided to explicitly add the noun '테마' (Theme) after the adjective, resulting in '어두운 테마' (Dark Theme) and '밝은 테마' (Light Theme). Although this deviates slightly from the structure in other languages by adding a word, I believe prioritizing clarity and naturalness for the target audience is the best approach here.

(Optional addition regarding 'Auto'): For the 'Auto' option, the Korean word '자동' (jadong) works perfectly well on its own because it describes the method of theme selection (automatic) rather than a specific visual style like 'dark' or 'light'.

And similarly here: most languages just include “Next”/“Previous” without specifying “page”. But if “페이지” here helps to clarify the meaning, then it’s fine 👍

This part is the same. By modifying the format of the original English expression, I removed the incomplete feeling from the Korean and added clarity and naturalness for the target users.
