Most color pooling yarns have color lengths between 6-12 inches, but when the lengths are longer, we can use "yarn eating" stitches like this granny stitch shown above. Other "yarn eating stitches" include the puff stitch, the bobble stitch, the popcorn stitch, and the jasmine stitch, to name a few. My swatches are normally 2 complete color sequences long, but for long color changing yarn, I usually only use half a sequence.
With longer sequences, you can make stunning blankets that crochet up very quickly. I love the colors in this Yarn Bee Soft & Sleek: Windswept Wishes shown above.
Some other popular long color changing yarns are Yarn Bee Soft & Sleek: Emerald Garden (done in puff stitch) and Winterberry Frost (granny stitch), Caron Simply Soft Times Square (granny stitch), Red heart Neon Stripes (granny stitch), Primary stripes (swatch to come) and any of the Red Heart Granny Square Yarns
Why don't you give it a try. I'm sure you'll be very pleased with the results.
