Line Chart - Inconsistent color scheme

Hi everyone,

I have a line chart showing the number of cases created/ closed within the day, and I want the color scheme of the trend lines and legends consistent, which are:

Case Closed: Blue,

Case Created: Green

I have a filter list for case type, and this is where I found the inconsistent issue.

For example: If I choose case type = 1, the color theme is consistent with above setting (Closed: Blue, Created: Green)

                      However, if I choose another case type = 3, the color is other way round (Close: Green, Created: Blue), which might confuse users.

If I set pre-defined color scheme different than CLASSIC (E.g. SUNSET), the color scheme will be consistent after applying filter, but then it become inconsistent again if there is any new closed/created case.

                a!queryFilter(
