Yo uso los excelentes cronosys. Por alguna razón, todos mis gráficos de colores se volvieron negros. Después de un prolongado ejercicio de depuración, rastreé esto hasta el uso de HTML como modelo en el paquete xcolor.
¿Estoy siendo tonto? ¿Hay algún error o debería evitar agregar la opción HTML (que sé que aquí no es realmente un modelo de color)? El color en todo lo demás no se vio afectado.

La versión actual de cronos está disponible en:
https://tex.stackexchange.com/a/342699/ (2016-12-06)
Tengo una alternativa a chronosysla que he utilizado para responder algunas otras preguntas. Aquí tienes un primer paso para usarlo en tu línea de tiempo.
\begin{tikzpicture}
[
chronos={%
timeline width=120mm,
timeline height=5mm,
start date=0-01-01,
end date=2016-12-31,
only years,
timeline no years,
period event line/.style={draw=none},
timeline line={shorten >=-20mm, -{Triangle Cap[length=20mm]}}
}
]
\chronosperiod [draw=red]{1000}{1999}{2\textsuperscript{nd} Millennium}(-2.5pt)
\chronosperiod [draw=green]{192}{476}{Eastern Roman Empire}(-2.5pt)
\chronosevent {1969}{steps on the Moon}
\end{tikzpicture}

Esto no produce resultados idénticos, pero puede adaptarse. (De hecho, es mucho más flexible de chronosyslo que es, eh, bueno... el código no es tan inteligible ni tan adaptable como uno podría haber esperado).
