Although this does use synthetic dyes, if the calculations are done accurately
all the dye is taken up by the fibre and the solution after dyeing will be
If it is an exact match you want for a protein fibre then using acid dyes will
allow you to get an exact and repeatable colour. It is also good for getting
dilutions of the same colour from pale to fully saturated and comes into its own

than just throwing everything in! I like to think of acid dyeing as scientific
dyeing and the more accurate you are the better the results.
