I want to keep the gray streaks at my temples while considering a different shade for the surrounding hair. What I cannot picture is how a deeper surrounding shade would change the contrast around those streaks. The examples I keep finding treat the whole head as one color and lose that particular detail. I found a reference for hair color try on but need a way to discuss the gray placement alongside the proposed surrounding shade. Would separate annotated pictures be clearer than trying to create one convincing finished image? Perhaps I should identify the gray sections first and then compare a small number of darker options. I do not expect an image to show exactly how my existing color would take dye. For anyone who chose to keep gray sections, how did you communicate the contrast you were aiming for?
