The coloring result was flawless, exactly according to sample the darkest tone accordingly and nice and even.
If splashes of dye on porthole or rubber gasket remain, removes the subsequent wash cycle, which is to take after dyeing with the colored clothes in any case yet.
In any case, the result of the color of laundry is dependent, these had before. How to brighter color actually not in principle, this should be clear before. White and bright colors such as yellow and beige can be surely re-color in green, blue or red, any other color output probably only to black, otherwise it can be scary.
To try this out once I had put a small portion in the machine, which was black / green striped. The black was black and so took the green a red hue to which one does not want to have now. That was virtually the proof, better recolor only white or light colors.
