Same yarn colour, but different dye lots?
Why not make it a part of the garments look?
On a sweater for example. Figure out if there is enough yarn of same dye lot to knit two sleeves of it. And if not, you might want to place it as a stripe on the yoke or the body. Or maybe you want to make something smaller?
Here is a tip for a hat. This hat is knitted with two different blue colours, one grey, and for the white part it is used three different dye lots.
The darkest colours are in bottom of the hat, and the lightest colours on top. So, the white yarn was sorted by which one was brighter. One can hardly see that they are different, and that was the point this time.
All the colours are knitted to the end of the thread and used up. Because of that the switching of colours will start on different places on the hat and make a softer impression of the shifts. Easy and fun.
