Paint source for purple midge

I9m looking for a source of spray paint for doing several interior parts of
my 74 1/2 midge.  The color is a dark purple, and I haven9t yet figured out
whether the color is aconite or black tulip.  In any case I was hoping that
I could purchase several spray cans of paint that would be close to the
color that I plan to respray the entire car (probably next summer some
time).  I plan to respray the vehicle with whatever color it now is since I
like it.
Thanks again,
