Shawl-itation

I've been busy knitting a shawl for the past four days. Now, it's time to add the second color and I'm hesitating. Here's the planned skein wound up and sitting in the middle of the shawl-in-progress.


The yarn I'm using is wool. I do have a similar weight of acrylic of each color already in there (hot pink, turquoise, and purple).

What do you think?

Should I abandon my multi-color project and fiber content to keep a consistent color palette?

Should I just go with the original plan and see what happens?
