Package	Signature	Allowed mode	Notes
`color`	`o:N m:N m`	math	Colors a single argument, used to highlight one term in a formula without affecting what follows; an optional model argument such as rgb, RGB, or gray gives the color numerically.
`textmacros`	`o:N m:N m:T`	text	Colors a span of text inside text-mode content such as \text; the colored argument is text and may contain inline math, and an optional model argument gives the color numerically.

TeXForm parses this entry as prefix syntax; the package determines its argument specification.
