Shale Carbon is a neutral and dark 2-colour linear gradient that runs from charcoal (#1F201F) to grey (#626A69) at 160°. It suits subtle surfaces and app backgrounds and dark-mode interfaces and footers. White text reads best on it, at a contrast ratio of 9.7:1 against the gradient’s average colour (AAA).
