Colleagues,
Shifting seamlessly from colour description to protocols for
registering colour in photogrpahs and digital images, there is one
readily available colour card for photographs that has been developed by
IFRAO [International Federation of Rock Art Organsiations].
It is a small paper card with colour patches and b&w bar sections. It
is internationally distributed and cheap [IFRAO forbids selling them so
they are given away]. Well-sized for close-up artefact work and ble to
be produced with enough consistency through print technology rather than
the need for absolute exactness that forces up the price of a
Munsell-style colour kit. There are Kodak grey and colour scales on the
market, but they are not cheap and you are reluctant to actually use
them, if only because it costs to replace them after they get dirty.
The link to the commentary on the scale is:

The link also provides an address for obtaining copies.
Potentially one of the few things that we could encourage as an
international standard in our work.
