Suffragette colour mix yarn?

[BoneAppleTeaa]

Hi all, I’ve been searching online but can’t seem to find something like this - where is best for me to look? Ideally the yarn will be cotton, but I could use acrylic. No animal derived fibres though. Thank you for your help!

I've found two variegated yarns on the Woolwarehouse site so far that roughly meet your criteria.

This Sugar and Cream Ombré in 100% cotton (Aran weight) and

This King Cole 100% cotton (4ply weight)

Thank you! The first one is probably closest but thinking I’m going to have to buy the three separate colours and do it that way.
