Power BI's visualizations have colors assigned automatically. It should be possible to set a color when a value is reached (e.g. always show negative bars in red) or for a particular color in a legen...
Yes! Please make sure we can specify colours based on built-in or custom themes (e.g. accent colour #1) or to override them completely by specifying a direct colour (either through a picker or by specifying the HEX value). So basically making the whole colouring experience more aligned to Office Applications. I second Sam Carroll's comments about Power View as well. It is quite embarrassing to explain to end users that we can't change the colour of charts. So this is something that should be pushed to on-prem deployments as well. Also since we are on the subject, please let us specify things such as borders and their sizes, line format, shape (e.g. round edges, etc).
