Developer panel

Scan the developer, choose the ratio, and Color Lab tells you straight away how many grams to add to the color in the bowl.

How to do it

Weigh the colors into the bowl as usual.
Scan the developer. A panel with five ratios appears.
Choose the ratio the manufacturer recommends and pour developer up to the number Color Lab shows.
