Description

Spot colours can be defined using three arguments instead of two arguments, like \definecolor. The first argument is the colour to define. The second argument is the colour to be use as a base. And the third argument takes the same options as \definecolor.

Example 1

\setuppapersize[A5]

% define the spot color for the plotter
\definecolor[CutContour][c=0,m=1,y=0,k=0]
\definespotcolor[Contour][CutContour][p=1]

% here is the outline feature
\defineeffect[outline][alternative=outer,rulethickness=.25pt]

\starttext
\startcolor[Contour]
\definedfont[Serif at 50pt]

\starteffect[outline]
Magic Outline
\stopeffect

\stopcolor
\stoptext

Example 2

    \definecolor     [ColourSecondary]             [h=9A957A]
    \definecolor     [ColourSecondaryLighter]      [h=9A957A, a=1, t=.5]
    \definecolor     [ColourSecondaryLightest]     [h=9A957A, a=1, t=.3]
    \definespotcolor [ColourSecondaryLighterSpot]  [ColourSecondary]     [a=1, t=.5]
    \definespotcolor [ColourSecondaryLightestSpot] [ColourSecondary]     [a=1, t=.3]

    \setupblackrules [height=1cm, width=5cm]

    \starttext

    \blackrule[color=ColourSecondary]

    %% defined using \definecolor
    \dontleavehmode
    \blackrule[color=ColourSecondaryLighter]
    \blackrule[color=ColourSecondaryLightest]

    %% defined using \definespotcolor
    \dontleavehmode
    \blackrule[color=ColourSecondaryLighterSpot]
    \blackrule[color=ColourSecondaryLightestSpot]

    \stoptext
