the color of sciview is also changed when changing its timestamp

We should find a way to avoid the color being affected by the change of timestamp.

In the current code, restoreVolumeColor function (https://github.com/mastodon-sc/mastodon-sciview/blob/dev/src/main/java/org/mastodon/tomancak/DisplayMastodonData.java#L264) is used to avoid color changing when modifying the time.
However, is there someway to avoid the change radically?
