The actual fabric looks closest to the first two photos and is not as quite as green as the third photo. This fabric has a medium-light green color with a yellow undertone and is definitely as warm green (not blue or cold). It’s closest match is Hoffman 1895-539 Parsley.
The first photo is one that I took and the second photo is the manufacturers thumbnail image. The actual fabric looks closest to the first photo and is more teal (Bermuda) blue than green. It is bright and strong like the first photo.
***UPDATED 12/05/22: The latest dye lot of this fabric is featured in the first two photos. Photos 3 and 4 are older dye lots in which the fabric appears much more fuchsia purple, lighter and with less teal in it. The most current fabric looks closest to the first two photos and is much darker with less purple and more teal and gray in it. It’s more jewel toned than previous dye lots and includes hints of lagoon blue dark mint green and warm and cold indigo colors.
