That is very blue, similar to shimmer lights. This is the reason behind "little old ladies with blue hair"
The reason bluing shampoo works is that the blue counteracts the yellow tints in the hair. the hair will "grab" the blue for this purpose. If there is too high a concentration of blue pigment in the hair, due to too high a concentration of shampoo or too many consecutive uses, it can and does stain the hair. The milder formula bluing you have pictured probably will not work as well against the yellow but you run less of a chance of that happening. You can probably dilute that stuff with another shampoo or add a dab of that to the other bluing shampoo for better results without the stain.
To remove the bluing sometimes it needs to be bleached out or sometimes a heavy conditioner will lift it enough. Also it will fade with time and bathings, and of course will grow out. The more porous the hair (usually the ends) the more blue will grab, but also will come out easier.
just FYI. I dont know if you wanted all that info
