Do we need to follow brand colors for data visualization?
I am working on a design language project for our product. I'm currently putting together a color palette for data visualization part of the app. Based on my research on colors for visualization and careful consideration of color theory, and accessibility, I came up with a set of colors (muted color palette) that would blend well with the UI. I worked it off the brand colors. Because our primary brand colors are Orange, Grey, and Green and ours is a typical network/device management app.
So, the question is: do we need to use brand colors for data viz?
Of course, the product UI conforms to the brand colors. However, I feel the chart colors not necessarily be restricted to the brand palette for a couple of reasons:
The marketing team which originally came up with the brand colors would not have thought about colors that would work well for Data viz. And I think they are more of a brand guideline that's suitable for the promotional/marketing material and for the corporate website. They don't seem to fit the bill for chart colors. We do have secondary and tertiary colors. So some of the colors I've come up with are derived from the secondary and tertiary colors and I've reduced the saturation level so that it's easy on the eyes.
It is an NMS app, orange and grey (primary brand colors) has some meanings in our app context (e.g., error, severity, others/unknown etc.,)
Should the chart colors represent the brand? Are there any guidelines on this? If someone could point me to some best practices, it would be helpful.
