Using this palette

Structured like graphite-and-lime — mostly neutral with one loud accent — but crimson reads completely differently from lime: aggressive and urgent rather than technical and modern, which is why this suits sports, streetwear, or breaking-news editorial branding specifically rather than dev-tool contexts. #D62828 against #0D0D0D clears very strong contrast and can carry both large CTAs and small accents, unlike lime which needed to stay minimal — crimson has more tonal range to work with at full saturation. White or off-white copy is comfortably legible on either #0D0D0D or #2B2B2B, which is enough by itself to run a full dark-mode build without the crimson at all.
