Each brand and competitor in a project has one colour, and it is the same colour in every chart that draws brands: the Competitors ranking dots, the share of voice lines and legend, and the Brand shape radar.
Colours are given automatically when a competitor is added. To change one, open the Brand colours card, which has one row per brand and eight swatches each. Only those eight colours are offered, so every choice stays readable.
How it works
A competitor keeps its colour when you add or remove others. Removing a competitor frees its colour for the next one added. With more than eight, colours are shared, least used first. Your own brand keeps the app's own colour until you choose one. The Overview and the report draw your brand's line in that app colour either way.
Where to find it
