Rainbow: Crochet Color Palette & Yarn Placement Generator

Compare seven slots with seven equal zones

This rainbow reference orders seven digital colors and applies them to a rising-and-returning stitch sampler. Its independent question is why an uneven finite palette grid can coexist with equal construction quantities per color. The palette contains sixty-four positions, while the companion contains seven two-row zones. Rainbow names this selected seven-color sequence; the artifact does not claim a scientifically measured spectrum or a physical yarn match.

Prepare a numbered seven-color key

Use smooth DK cotton candidates and begin with a four-millimeter trial hook. Have scissors, a tapestry needle, zone markers and a ruler ready. Enter rust #C44833, orange #D97832, gold #C29524, green #526B45, blue #267E9D, indigo #243BCE and violet #704A8E. Keep tags numbered one through seven and use US terms. Different materials bearing those color names must still be compared physically for thickness, care response and suitability for the same sampler.

Explain the palette's remainder

In the fixed eight-by-eight reference, the first slot occupies ten positions and each other slot nine. Seven does not divide sixty-four evenly, and the row-plus-column cycle's starting phase determines which slot receives the extra position. Neighbor luminance ratios are 1.55:1, 1.14:1, 2.15:1, 1.28:1, 1.76:1, 1.18:1 and 1.41:1. None of those grid quantities specifies a row count or yarn amount for the construction below.

4. Color 4: #526B45; next-color luminance contrast 1.28:1. Assign to rounds 4, 11, and repeat.
5. Color 5: #267E9D; next-color luminance contrast 1.76:1. Assign to rounds 5, 12, and repeat.
6. Color 6: #243BCE; next-color luminance contrast 1.18:1. Assign to rounds 6, 13, and repeat.
7. Color 7: #704A8E; next-color luminance contrast 1.41:1. Assign to rounds 7, 14, and repeat.

Restore seven explicit sampler zones

The companion uses thirteen stitches across fourteen rows. Its saved custom plan is sc:2, hdc:2, dc:2, tr:2, dc:2, hdc:2, sc:2, with yarn changes by zone. This creates two rows each of single, half double, double, treble, double, half double and single crochet. Every zone has its own palette slot. The plan's input codes remain US codes even if output terminology is later changed; they identify the requested operations rather than translated prose.

1. In color 1 (#C44833), ch 14. Starting in chain 2 from hook, work 13 sc.
2. Ch 1, turn (turning chain does not count). Zone 1, color 1 (#C44833): work 13 sc, one in each old stitch. Complete the final pull-through in color 2; cut the old color leaving a weaving tail. Next turning chain uses the new yarn.
3. Ch 2, turn (turning chain does not count). Zone 2, color 2 (#D97832): work 13 hdc, one in each old stitch.
4. Ch 2, turn (turning chain does not count). Zone 2, color 2 (#D97832): work 13 hdc, one in each old stitch. Complete the final pull-through in color 3; cut the old color leaving a weaving tail. Next turning chain uses the new yarn.
5. Ch 2, turn (turning chain does not count). Zone 3, color 3 (#C29524): work 13 dc, one in each old stitch.
6. Ch 2, turn (turning chain does not count). Zone 3, color 3 (#C29524): work 13 dc, one in each old stitch. Complete the final pull-through in color 4; cut the old color leaving a weaving tail. Next turning chain uses the new yarn.
7. Ch 3, turn (turning chain does not count). Zone 4, color 4 (#526B45): work 13 tr, one in each old stitch.
8. Ch 3, turn (turning chain does not count). Zone 4, color 4 (#526B45): work 13 tr, one in each old stitch. Complete the final pull-through in color 5; cut the old color leaving a weaving tail. Next turning chain uses the new yarn.
9. Ch 2, turn (turning chain does not count). Zone 5, color 5 (#267E9D): work 13 dc, one in each old stitch.
10. Ch 2, turn (turning chain does not count). Zone 5, color 5 (#267E9D): work 13 dc, one in each old stitch. Complete the final pull-through in color 6; cut the old color leaving a weaving tail. Next turning chain uses the new yarn.
11. Ch 2, turn (turning chain does not count). Zone 6, color 6 (#243BCE): work 13 hdc, one in each old stitch.
12. Ch 2, turn (turning chain does not count). Zone 6, color 6 (#243BCE): work 13 hdc, one in each old stitch. Complete the final pull-through in color 7; cut the old color leaving a weaving tail. Next turning chain uses the new yarn.
13. Ch 1, turn (turning chain does not count). Zone 7, color 7 (#704A8E): work 13 sc, one in each old stitch.
14. Ch 1, turn (turning chain does not count). Zone 7, color 7 (#704A8E): work 13 sc, one in each old stitch.

Audit equal quantities without claiming equal fabric

Thirteen stitches per row and two rows per zone give twenty-six completed stitches per color. Seven zones contain one hundred eighty-two stitches altogether. The two single-crochet zones contribute fifty-two stitches, the two half-double zones fifty-two, the two double-crochet zones fifty-two, and the central treble zone twenty-six. Turning and foundation chains are separate. Equal completed-stitch counts do not imply equal yarn meters or equal washed zone heights across those stitch types.

Keep the slot-to-zone transfer explicit

The palette's written assignments are expressed as a repeating round cycle. The sampler instead saves seven color zones, each lasting two flat rows. The companion's working-color labels and yarn-change instructions make that transfer explicit. Do not read the first palette's ten rust cells as ten sampler rows. At each zone transition, follow the final pull-through and upcoming turning-chain instructions, and retain finishing allowance for the resulting yarn ends.

Questions before extending the sequence

Can fourteen rows certify a physically symmetric fabric? The height sequence returns, but actual tension and care behavior must be observed. Does the first slot's extra planning cell require more rust yarn? Its sampler zone still contains twenty-six stitches. Save both files with the seven tags and consult the gauge guide when comparing transitions. No physical rainbow sampler, identical zone height, measured shade match or equal per-color consumption is claimed.
