Colours for the whole wall. All of the built-in palettes use fully saturated fills and pick black or white text automatically from the measured contrast, which is what keeps them readable on a television seen from across a room. Colour-blind safe replaces the usual green/red pair with blue/orange and adds a hatch pattern to failing and unstable tiles, so the wall still reads without colour vision. Daylight is the one to try if the screen faces a window.
