'Clair' means bright, bright, and clear in French.
As its name, Sandoll Clair Sans has a more cheerful and bright impression compared to the existing Hangul gothic typefaces.

In order to give a rounder and fresher impression, the inner space was secured by further emphasizing the flexibility of the curves on the curves such as ‘나’, ‘다’, and ‘의’. In the same vein, the curves of ㄱ, ㅅ, ㅈ, and ㅊ, were slightly more emphasized. In order to avoid hard looks a little bit hard, ㅅ,ㅈ, and ㅊ have an asymmetrical structure. ㅇ pushed the inner space of the four corners of the ellipse to the outside to widen the inner space a little bit. The complex graphemes, such as ㅃ or ㅆ were simplified to help to give a clean impression.
Although the handwriting order was somewhat reflected in some grapheme, the overall skeleton is not much different from the Hangul gothic, and obtrusive expressions were avoided. Latin is based on Sandoll CompSans but has been slightly modified to fit Clair Sans Hangul.

If you are looking for a Hangul gothic font that has some features compared to the existing gothic ones but not too much, try Clair Sans!
