Inspired by London at dusk, this dark theme rests on a slate grey base washed with twilight indigo, then lights it with the pillar box red of a K6 telephone box and the muted steel blue of the Thames. The calm grey surface keeps long sessions easy on the eyes while the red accents mark what matters.
