It is possible to changes the default color (Blue) in all the Column Charts. I would like to set an other color that is more suitable to my company Branding but I do not want to do it every time I make a new visualization.
Thank you for the help
I am pretty sure this is not possible at the moment.
There is a year old idea at ideas.powerbi.com that is requesting this and there it says it was planned for 2015. But they usually have another status (started) for when they have started implementing it so I wouldn't get my hopes up just yet.
I haven't found any workaround for this unfortunately.
