You buy dye and salt. Then simply run in in the washing machine... it's kinda expensive so it's wise to dye a lot at the same time.
Put the small parts in a net if they are so small they might get into those holes...
You could dye clothes at the same time of course... imagine it Millzy, ALL your white Ts could be pink... (and all of your girlfriend's white lingerie of course

)
The saucing pan trick could perhaps provide a darker shade of course...
