I think that npmjs uses colors too much to the point of irrelevance. Why are links in the README red? Why is the code tab red? Why is the download graph purple?

Compare your npmx link to vue to https://npmx.dev/package/node-red-contrib-rtc-alert-node . This package uses deprecated and vulnerable deps and npmx correctly uses color to draw attention to it. And because the npmx page is normally monotone, the use of color actually draws your attention.

Regarding clutter - I agree.
