I have a friend who buys thread for her knitting and needlework. When she runs out, she buys more, even while in the middle of a project. And manufacturers are not always spot on.
Those of us who can discern the difference between the colors safflower and daffodil cannot explain to her that yellow is not yellow. Like her, most people cannot discern the fine color differences even within dyes but between batches.
To look at her work is to be stunned by its artisanship, but its chromatic cacaphony is painful to look at.
How do you give the blind sight?
