I haven't ever used it on my van, but the type of silicon caulk
for household use cannot be dyed after manufacture.  When I was
filling cracks in the stucco on my house, I ended up using latex
caulk for that very reason.  It is not as durable as silicon, but
can be colored by the consumer.  Make sure it's UV resistant if
it will be exposed to sunlight.
