Every grey is the background stepped toward the opposite pole (white on a
dark theme, near-black on a light one), so a host theme with a blue-black
background gets blue-black panels rather than a neutral grey pasted onto
it. The accent is the theme's line colour, the up and down pair are the
candle colours, and text comes from the axis text colour lifted for
legibility: the axis is deliberately muted on the canvas, and a panel label
at that weight reads as disabled.
