Use HSB not RGB because it is the way we think. That is hue: the color, saturation: how strong the color is, brightness, how dark/light the color is. If you use RGB and are asked to make the color less saturated that is going to be a problem, in HSB it is intuitively easy. Consider that Apple used 215° hue extensively but with different saturations and brightness.

Really bad UX design choice. 1) Going to an article breaks "Open in New Tab". 2) Not what is expected based on decades of usage. 3) No clear way to get back. 4) The full site flashes in as the page is scrolled.
