Can someone explain why in the last example the pdfliteral messes up the spacing

\pdfcompresslevel=0

\setupcolors[state=start]

\starttext

\def\red  #1{\pdfliteral {1 0 0 rg}#1\pdfliteral{0 g}}
\def\green#1{\pdfliteral {0 1 0 rg}#1\pdfliteral{0 g}}
\def\blue #1{\pdfliteral {0 0 1 rg}#1\pdfliteral{0 g}}

\dorecurse{25} {\red{red} \green{green} \blue{blue} }

\def\red  #1{\pdfliteral direct {1 0 0 rg}#1\pdfliteral{0 g}}
\def\green#1{\pdfliteral direct {0 1 0 rg}#1\pdfliteral{0 g}}
\def\blue #1{\pdfliteral direct {0 0 1 rg}#1\pdfliteral{0 g}}

\dorecurse{25} {\red{red} \green{green} \blue{blue} }

\def\red  #1{\pdfliteral direct {1 0 0 rg} #1\pdfliteral{0 g}}
\def\green#1{\pdfliteral direct {0 1 0 rg} #1\pdfliteral{0 g}}
\def\blue #1{\pdfliteral direct {0 0 1 rg} #1\pdfliteral{0 g}}

\dorecurse{25} {\red{red} \green{green} \blue{blue} }

\def\red  #1{\pdfliteral direct {1 0 0 rg}#1\pdfliteral direct {0 g}}
\def\green#1{\pdfliteral direct {0 1 0 rg}#1\pdfliteral direct {0 g}}
\def\blue #1{\pdfliteral direct {0 0 1 rg}#1\pdfliteral direct {0 g}}
