Why does one visual keep diverting from theme colors?

The legend for both photos is the same column, but the values itself will be different. The column is 'event name' so it's team + day played. When I filter by team, they will each play a different day, but there's still a maximum of 3-4 values that the visual will show. I'll try pulling different colors into the theme, but I'd like it to be more consistent even though it is monotone.

So, the first visual could have July 1, July 2, and July 3, but the second visual could have August 1, August 2, and August 3. Does that make sense?

That being said I'm trying to find a way to force Power Bi to use the colors in the theme to avoid this. I know it's monotone, so I'll try pulling in some different colors into the theme, but
