The link color on the white background is difficult to distinguish.

[Antoliny0919]

The current link color on the white background does not seem appropriate from an accessibility perspective.
Even without color blindness, I find the link color almost indistinguishable from the regular text color.
I think the link color should be a bit darker.
Also, from an accessibility standpoint, underlining links is recommended. However, since there are many links on the current website(Homepage) and they are integrated with the text, adding underlines might negatively affect the visual appearance.
(I think it would be better to separate the website sections into columns first and then consider adding underlines later.)
