# Objective allow specifying the left/top/right/bottom border colors separately for ui elements fixes #14773 ## Solution - change `BorderColor` to ```rs pub struct BorderColor { pub left: Color, pub top: Color, pub right: Color, pub bottom: Color, } ``` - generate one ui node per distinct border color, set flags for the active borders - render only the active borders i chose to do this rather than adding multiple colors to the ExtractedUiNode in order to minimize the impact for the common case where all border colors are the same. ## Testing modified the `borders` example to use separate colors:  the behaviour is a bit weird but it mirrors html/css border behaviour. --- ## Migration: To keep the existing behaviour, just change `BorderColor(color)` into `BorderColor::all(color)`. --------- Co-authored-by: ickshonpe <david.curthoys@googlemail.com>
