You get a list of defined color names in 'xwi' with:
attributes.colors.setlist("xwi")
Anyway, "whatever action I want" is somewhat vague, for instance you the
vebose spec with:
attributes.colors.values[name]
but there's more. There might be better ways to achieve what you need it
for.
Here is a nostalgic mkii accessor for such a list (color support is a
real old feature and conceptually hasn't changed that much):
\def\WhateverActionIWant#1{#1\par}
\settrue\collectcolorsinlist \setupcolor[xwi]
\processcommacommand[\colorlist]\WhateverActionIWant
but you probably don't want to catch up on that.
