stripe
縞 centers on a pattern of parallel lines or bands: a stripe. It is used for striped fabrics and similar linear markings.
縞 combines 糸 (thread) with 高, which likely contributes the sound and may relate to the idea of raised or distinct lines, giving the meaning of striped fabric.
Thread 糸 woven with a tall, distinct pattern 高 creates stripes. Imagine a loom producing fabric with clear raised lines.
For コウ, picture a bolt of striped cloth being carried by a courier: courier -> コウ, and the stripes are woven into the fabric.
