Set Custom Colors for Strategic Roadmaps

What is the challenge?

I can't present a cohesive connection between my initiatives and timeline through colors like I want.

What is the impact?

Medium impact - my roadmaps are less effective and require additional work to present. Difficult to share asynchronously.

Describe your idea

I'd like the ability to color both my initiatives and my releases, and set a color gradient. For example, releases that contain features in multiple initiatives should all be blue. Across different initiatives, they would be various shades of blue. If coloring were custom, this could be achieved according to a number of color schemes.
