It can be Indigo-Carmine, Prussian blue, soluble blue Parisian, blue aniline dye. Prussian blue dissolves in water only in the presence of oxalic acid. Aniline dyes are usually the most expensive. They have good paintability, but can discolour in the sun. Some aniline dyes after using the iron become red. Among the aniline dyes that are suitable for the production of blueprints: methyl, methylene blue, and wool.
Ultramarine refers to insoluble species of the blue. It's a pretty cheap product. You should know that soluble dyes color the fabric is much more uniform than insoluble.
To make the solution blue need in accordance with the instructions on the package. Because some things are colored in the wash in blue and some in the rinse cycle.
