Red at full strength. #dd0300 is a vivid, saturated red with almost no orange in it, so it reads hot and loud rather than earthy. Use it as a call-to-action button, sale badge, or small accent, since a full background can overwhelm. White text on this hex code passes AA at about 5.1:1 contrast, so it stays readable. Navy and charcoal give it room to breathe.
