Message: i am trying to tie dye red, black, navy and brown bikinis to a different fun color. is that possible to do? ho can we tie dye color fabric?

Dyes can make fabrics darker, never lighter. You cannot dye black, navy, or brown into any fun (i.e., bright) color.

You can paint them with metallic fabric paint, such as Lumiere, or opaque fabric paint, such as Neopaque. One source of such fabric paints is http://www.dharmatrading.com . This is the only way to make the bikinis more fun in color. Most other fabric paints are transparent and will work only on lighter fabric colors.

What dyes can be used depends entirely on the fiber. Different fibers require different types of dye. Polyester and acetate are no fun to dye. Cotton and nylon can be dyed with different dyes.

It is best to start with white or light-colored fabric, if you wish to tie-dye.
