"Unsafe" colour
This site makes extensive but careful use of colours not in the
"browser-safe" palette of 216 colours. We have applied the advice
given in our Colour Selector
resource, where we encourage people to loosen their grip on the 216
palette since only a small minority still have 8-bit video cards.
Colours specified in HTML or CSS (that is, not in graphics), never
dither; on video cards limited to 256 colours, they will shift to the
nearest colour in the 216 palette.
The table below shows the colours used in this site against the nearest
"safe" colours. Each row shows the swatches for a section. The left-hand
block of colours show the original colours as specified. The right-hand
block of colours show the nearest colour of each original colour.

However, for any given row in the table (representing a section's colours),
the hue is consistent - unsafe colours are set to shift to relatively
different colours when not doing so would be confusing.
