Poor visibility of the selected color

[FromSi]

When I choose a tool, I understand it. When I choose a color, I don't understand it. Firefox: Version 83.0 (64-bit)

P.S. Error: TypeError: undefined has no properties Script: https://pixelcraft.web.app/ Line: 528 P.P.S. After UNDO-REDO, the editor chooses white.
