This was raised by 2 customer page/model builders (who were guest presenters in yesterday's Nordic Anaplan Group workshop) - I submit to Idea Exchange on their behalf:
It is very good that Anaplan Management Reporting allows builders to select any colors so that they can use the customer official color palette, thank you. However, please enhance Anaplan to remember + store the colors used. Right now, every time we want to select a custom color we must reenter the hex code every time, even if we have used the same color 2, 10, 100 times in the last hour. Actually, the ideal would be to create a predefined palette consisting of our corporate colors.
