Summary

The command \setupcolors is used for general color settings.

state	start stop
spot	yes no
expansion	yes no
factor	yes no
rgb	yes no
cmyk	yes no
conversion	yes no always
pagecolormodel	auto none name
textcolor	color
intent	overprint knockout none

Option Explanation

state

Switch colors on or off globally.
stop	All colors get converted to greyscale.

spot

Allow spot colors (for printing with more than CMYK, also for varnish)
no	Defined spot colors get converted to RGB or CYMK

rgb

Allow RGB colors

cmyk

Allow CMYK colors

pagecolormodel

auto	Prevent some issues with transparency

textcolor

Global main color for text

intent

This sets the complete document (global) to overprint (or knockout) and is only useful for grayscale-only documents.

Don’t set this parameter if you want to use local overprinting (or knockout)!

This setting is far older than the PDF/X or PDF/A related output intent parameter in \setupbackend, and there’s no direct relation other than that both parameters are prepress options.
