Ok, so I know that these really look like two totally different pieces of knitting. They aren't.
Indoor light vs natural light.
Blue binding vs light green.
Over thinking your color choices vs going with your first instinct.
Questionning my color instinct, which I actually think is usually pretty damn good, I returned the light green Koigu I originally bought and bought the Caribbean Blue Louet's. It looked like a good match for the blue splashes in the yarn. In reality it was horrible. In lights other than Rosie's it wasn't green enough. The contrast was too great. And with all the varigated Koigu it was too solid.
Ripping back my knitting ranks right up there with unmedicated root canal. It hurt like hell, but I am incredibly happy now...reunited with my light green Koigu.
