Core How-Tos
Paste without the colors
Text copied from a dark-mode page carries its colors with it. Copy:Paste+ drops them as you paste, so what you paste looks the same whatever it was copied from.
Why pasted text goes wrong
Chrome puts the colors it sees into the clipboard along with the text. Copy from an AI assistant, a docs site or a chat in dark mode and the pale text and dark backgrounds come along. In a dark editor it can look normal; whoever reads it on white finds a black block, or text that seems to be missing.
Paste as usual
Cleanup is on from the start. Paste with Ctrl+V (⌘V on a Mac) as you always have: colors and backgrounds are dropped on the way in, and bold, italics, headings, lists and links stay.
To switch it off for a moment, click the toolbar icon and clear Clean pasted formatting. The same switch is in Settings → Pasting, under Pasted formatting.
Where it works
Rich-text editors on any website, in every frame: anything editable in place, such as mail composers, document and ticket editors, and chat boxes that keep formatting. Plain text boxes never hold formatting, so there's nothing to clean there.
Chrome doesn't let extensions run on its own pages or the Chrome Web Store, so pasting there is left alone.
Set the font and color too
Pasted text takes on the editor's own font and color unless you pick one. See Choose the font and color of pasted text.
