# 02-structure

<<you>>
The indigo body reads heavy and flat in the middle. Could you show me a few different ways to give it internal structure — lighter veils or threads inside the ink — so I can pick one?

Three checked previews are shown above; **the live version is unchanged**.

- **A — Soft veils:** smoky blue layers reveal broad folds inside the ink. Softest and most watery, though it lightens much of the center.
- **B — Fine threads:** delicate pale-blue filaments weave through the interior, preserving the deep indigo body. Most detailed.
- **C — Warm channels:** wider, warm lilac ribbons divide the ink into dark pools. Bolder and more marbled.

All three preserve the original outline and slow, in-place evolution, previewed at **0, 8, and 20 seconds**.

My pick is **A for softness**, or **B to retain the ink’s depth**. Which would you like to use or refine?
