Does anyone here dye cloth? Need advice.

As the title suggests, looking for help with a possible dying job I want to try

I've worked with fabric for many years but I've never tried dying any of it... (it seems like a really messy process and I just can't deal with messes)

I've dyed cloth in the past, with Rit dye.It was pretty easy.

So here's the project: I have this jacket https://www.lee.com/shop/mens-chore-coat-22024.html?merchCategory=LEE_MEN_CLOTHING_JACKETS&dwvar_22024_color=2202401

I also ordered it in the brown as a work/hunting jacket but decided the brown was much better for wearing out and about. I'd like to save money and dye the blue one some sort of olive/brown drab earth tone. Maybe a base of yellow and some brown?
