First choose the depth
Decide whether you want your hair to read darker overall, remain close to its current depth, or include lighter pieces. A reference can look almost black in shade and much lighter in sunshine, so bring more than one lighting example when possible.
Then discuss the tone
Words like chocolate, espresso, and chestnut can mean different things to different people. Point out the specific warm or neutral qualities you like. Your colorist can translate those preferences into a plan based on your starting point.
Keep the change intentional
If you are also planning a haircut, discuss the cut and color together. Pieces placed around the face may change position after length comes off. Confirm the service order and what the finished outline will be before either begins.
Use these ideas to get curious and find what you love. Your stylist can help turn the inspiration into a plan for your own hair. AI previews and salon results can look different; these guides offer ideas, not a personal stylist assessment.
