I'd bet against it being a success-- blinds are usually made of a fabric that specifically resists stains [which is what dye is, after all], or treated with something to get the same effect.

Plus, with a vertical you are going to want the whole thing the exact same color, and people can see the whole thing at the same time. With a shirt [say], no one is going to see the front and back at the same time, and any variation will likely be attributed to the angle of light, etc.

I think it's a waste of time. As oruboris said, most are a polyester or nylon.........depending on the brand.

Why not just order new vanes. I've changed mine out before by ordering new vanes and using the original track. If you have a slim line track you can probably paint it if you need to change its color.

Everything you read on the last 2 postings are true.
I work for a major manufacturer of vertical blinds and
the fabric will not dye well. You may be able to order
new vanes but you will need to make sure the clips will
work on the track you have or if using the old clips
remove them carefully as sun damage make them brittle.

Now being the thrifty crafter I am, how about using a
fabric adhesive spray glue and putting a new fabric over
the old. Just choose one that does not fray or use fray check on the edges before gluing. Happy Decorating!

How did u go
