You can set colours by name:
https://github.com/BlackEdder/ggplotd/blob/master/source/ggplotd/colour.d#L20

Alternatively you can pass through the RGB value (see the link 
above for the specification).

Finally if you have multiple curves and don't want to specify 
specific colours you can just give them a different identifier 
(e.g. different double/int value (any type should do)) and it 
will chose the colours according to the colourgradient used. 
There is an example on how to specify your own gradient in the 
hist3D.svg example:
