Everyone knows that buying yarn online is not always WYSIWYG since colors vary by monitor calibrations and camera and lighting and other factors. I knew this, and still I took a risk in buying what is possibly the ugliest colorway in a yarn I've ever seen in person: Rowan Plaid in Soft Kelp.

Be not fooled by the subtle flecks of yellow in that photo, as in reality they are lurid snot green! Yes, the color of green snot! So now I'm knitting a shrug with 4 balls of this stuff and kicking myself in the derriere mentally for buying it without really getting to see it in person first.
I don't mean to knock on purchasing yarn online by photo in general, sorry if I come off that way in this topic. I've definitely had winning purchases as well.
Anyone else have some not-so-delightful colorway purchases from online photos?
