We are ultimately trying to push visualizations to small pricing displays (ImagoTags) that only accept black (#00000), white (#FFFFFF), and red (#FF0000). We build our Power BI visualizations in Desktop and select only these colors, but due to the aliasing (the greys that surround the fonts and lines if you zoom in), the images aren't coming out as true black and white and therefore aren't displaying correctly on the displays because of all the greys.
Anyone know if there is anyway to turn all that off and truely render a true B&W image? I doubt it, but wanted to see...
I'd like to suggest you create a custom theme file to setting global color for all visualizations.

I think it is hard to achieve your requirement to setting full color, maybe 'Transparency' property can help you reduce these effects.
