Having found out the true value of a colour card over a week ago when I ordered thread to match some Oakshott colourshott FQs from Aurifil using their colour card, I knew that there was nothing for it but for me to get myself a Kona colour card too.
Okay, now I know why they make these things. (a) So we can see the variances of shades between the colours and get just the right one we need, and (b) so that I would covet more and more solids. I need (yes, need) some azalea, cyan, citrus, sour apple, torch... ... and the list goes on. It's like being tortured by colour.
