Samples are slowing progress

My plan was to start digging into the 400 yards today. If I do 20 yards per day for four days, take a day off, then repeat five times, I'll hit 400 by May 25. I do have 20 yards done, but they are 'extra' yards. Not counting them yet! Anyhow, the picture at left shows two tests on the left next to two supplied swatches on the right. Tonight I did two more to try to match the bottom blue. I got the value better, but still not there with the color. It's also one of those blues that shifts according to the light. Using the Verilux lamp makes it look closer to violet.
I'll keep you posted on my progress - good and mediocre!
