+# [222_54]: Changed graphical selection from blue fill to black border(#2963)
 
-## 如何测试
+### What
+Changed the Graphical Window selection color to transparent and its instead indicated by a black border 
 
-```shell
-bin/test_only 222_54
-```
+### Why
+Currently, when a user clicks or selects a graphics canvas, the editor applies a semi-transparent blue fill over the entire area. On large canvases or complex drawings, this fill obscures the content and makes it difficult to see the grid or the objects being edited.
+
+### How
+In `src/Edit/Interface/edit_repaint.cpp`:
+1. checks if the current selection is inside_active_graphics().
+2. If true, the standard selection fill is bypassed.
+3. Implemented a manual 4-line border drawing using ren->line based on the rectangle's bounding coordinates (x1, y1, x2, y2) instead of the filling
