Flicker
is a male courtship signal - the
indication of intention to mate by
passing spermatophores. This display
has a pastel background which,
depending on the observer, is
described as iridescent pink, lilac,
purple or blue-grey. Additionally,
waves of chromatophore expansions
and contractions pass over the
body’s surface rapidly, making a
stroboscopic effect. Stripes can be
superimposed on it.
