   Committed dark page. Slate blue and deep navy are their own working colours;
   the safety orange is sampled from the crew shirts in p04/p05 and is the only
   action colour. The gold is the mark's own colour and is used only on the mark
   and on the installation figures.
   Corner radius is 0 everywhere. */
