Reply To: Indesign Spontaneous Swatch Change

Actually, I just tested and the Profile Mismatch dialog box (when opening a document) doesn’t offer “convert to profile”… my mistake.

But if the color management policies (inside Edit > Color Settings) were set to Convert to Working Space, this problem might happen when you opened a document. Swatches could change. (Not normally that dramatically, but certainly enough to be a shock.) In general, you want the policies to be set to Preserve Numbers (ignore linked profiles).
