Function part_color 

pub const fn part_color(part: Option<CellPart>, palette: &Palette) -> Color32

The colour a cell of this part takes.

CellPart is #[non_exhaustive], and a member added upstream lands on content: a part this renderer has not learned draws as text, which is a cell rendering plainly rather than a build that stops. Grep this when adopting a new makeover-layout.
