Time to have a little whine and a moan

Why can't yarn houses sell a good, solid purple?! Whyyyyyyyy?!!!

I don't have my camera to hand, (unfortunately), so I can't show you the purples that I've ordered from online, and compare how they actually look in the skien.

Online, the purples are either very deep (like Phildar's purple in their bamboo yarn) or very bright (like Brown Sheep's Fleece Yarn for 'raging purple'.

Only, when I get my yarn it's the blandest mid tint of purple that I've ever seen.

Can anyone give recs for a good and deep purple/eggplant/auberginey yarn? I'm too dark to be wearing midtint purple.

Thank ye. Preferably in 4ply or dk.
