This month we added the ability to format text fields based off a numeric field: https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-may-2018-feature-summary/#conditionalFormatting
We also are planning on adding a feature that will let you format your text based on comparisons. I’ll update this idea based on our progress on that feature.
