Revert "Use color extraction for arrow popup."

This reverts commit 242c805f8269d65391f257deb062969910f791b6.

Reason for revert: Introduces a leak. I haven't seen a bug for it yet, but this CL is the only in the culprit list; the leak can block multiple teams presubmits, and the leak is via ArrowPopup. Enough evidence.
