How to add color and alignment on the text tile Title and Subtitle?

[ramenos]

Hi. Beginner user of Looker, I’m trying to see I can change the color of a title (text tile) and align this same title on the left? I need to do this to enhance the storytelling effect of my dashboard but I don’t know how to do it.
I saw the documentation with Markdown but it does not seem to contain what I need (https://docs.looker.com/dashboards/using-markdown-in-text-tiles). I also read documentation about parameters but I did not find what I need (https://docs.looker.com/reference/dashboard-reference/lookml-visualization-reference/text-params).

Is it something you could help me with? It’s the last part of the dashboard I’m creating.
