I know the frustration of wishing you could see in-person the color of the fabric before purchasing. In today's world, for so many reasons, it's just not possible as we are driven to purchase more of what we need online.
As a fabric seller I have pondered this problem for the past few years, thinking if only you all had a Pantone color chart (lower left) it would be easy to identify color before buying, A Pantone chart costs $75 and up so it is not a practical price point at all!
What if a color chart was only $4.99 and readily available everywhere? Well here's my plan: I have purchased a 96 color box of Crayola Crayons and I will soon identify many fabric colors by using the Crayola color names. I am sure there will be some colors hard to match but with so many to choose from we can always get close. Pick-up the 96 color box of Crayola crayons and watch for crayon colors to start soon (see the first below).
