Compile with ramp color for each piece

[scorpes]

This is what I'm trying to do: Compile with for each loop and a ramp from attribute in a wrangle looping a color through each piece.

The for each loop works correctly and every piece get it's own color from the ramp. The compile sop compiles without errors but the colors for each piece part is not working in combination with Compile

Any idea how to fix this?

Here is a screenshot from the setup:
