Signals solid in the orange of the Signals icon's point (#268)

--accent2 mixed a quarter into the ground came out salmon, and is pink
or blue in other themes. Each Signal's tile is now solid #ff6a1a, or
#ff5500 in light, the point of signals.svg and signals-dark.svg, in
every theme as the icon is, with the icon or initials in the logo's
navy (#0c2238, 5:1 or better on either).
