Curated DarkBoldNeon

Argon is a dark, bold and neon 3-colour linear gradient that runs from near-black (#03001E) through purple (#7303C0) to pink (#EC38BC) at 135°. It suits dark-mode interfaces and footers and banners and attention-grabbing headers. White text reads best on it, at a contrast ratio of 9.4:1 against the gradient’s average colour (AAA).
