Photographing my yarn samples with a Colortrax color card for reference. My thinking is, if you have a copy of the card, you can adjust your monitor to match, to see accurate yarn colors.
I shot the pictures by setting a custom white balance with the color card, so the color is consistent. Next time, I'll have to use manual exposure/shutter speed to insure consistent brightness, as well.
The name of the yarn is under each photo set.
Tamm 3 Ply Astracryl
#1-2 Jaggerspun Maine Line
#3-5 Jaggerspun Super Fine Merino
#6-8 Jaggerspun Zephyr
#9-12 Jaggerspun Green Line
#13-16 Tamm Cotton Perle
#17 - 20 Tamm Petit 2/30
(My blog interface turns out to be not so great at rearranging groups of photos, so I'll try sorting them before uploading next time.)
Please note: I'm not selling or endorsing these yarns or the color card.
