URL: https://github.com/apache/superset/pull/38473#issuecomment-4054488897
## **Sequence Diagram**
This PR fixes time shift color matching by normalizing additional derived
series name patterns before color assignment. As a result, original and
time-shifted series now resolve to the same color key across line, bar, and
area charts.
