Hello guys,
I know that its not recommended to use inks from different brands - but - are they talkin about colours (green, red, yellow etc...) or inks at all? Can I use for example "tribal xxx black" from Panthera and "dark red" from Eternal? And can I also use some Silverback ink for shadows?
Normally Im using Panthera for lines and Silverback for shadows ...and everything is absolutely allright
so what do you think if I add some dark red from eternal?
