I received a great question in the Quilting Jetgirl Facebook group regarding the Wayward Transparency Quilt Along fabric selection: How much contrast is enough? Let’s look at some real life requested examples and discuss!
Above are are two potential Kona color palettes, photographed and evaluated as close to true color as possible.
Above are the same two images in grayscale. Note that grayscale implies Black and White but with no additional filters or alterations; it is only the removal of color.
Examining both the color and the Black and White images, the color value between Wisteria and Amethyst (images on the left in both sets) is very subtle, and in this case would probably create a less effective transparency effect than the color value separation achieved by the Orchid, Amethyst, and Navy combination (on the right).

Above are the second two images in grayscale.
Examining both the color and the Black and White images, the color value between Berry and Eggplant (the images on the right) is very subtle, and in this case would probably create a less effective transparency effect than the color value separation achieved by the Wisteria, Plum, and Purple combination (on the left).
Adding one more layer of refinement to the second example, I also urge consideration of fabric color tone. I would suggest swapping out Plum for something like Kona Crocus, which still reads as an effective mid value but blends in between the color tones of Wisteria and Purple.
Here is a very interesting example using prints. The light and medium value fabric have very similar background tones, but the medium value print has darker elements that are very consistent and at a small enough scale that it should make an effective and interesting combination.
I have purposefully shied away from trying to write a tutorial on how to create a grayscale image in software because there are so many different kinds of software and they are constantly updating. If you are really stuck, I suggest searching Google for:
