Our maggots are about 3 Euros per half litre and this is in any colour,
I've
never tried to colour them myself because they are so cheap, personally I
prefer natural (just plain white) maggots as this is a more natural bait,
IE
something that wild fish would eat occasionally when carrion floats to the
surface and becomes home to millions of fly larvae.

As Derek said, you will have to get rotten meat and add food colouring to
do
it properly, but the methods I mentioned would give you a tinge of colour.
