Page quality is a separate grade assigned by CGC and CBCS to graded comic books, indicating the colour and brittleness of the interior pages. The scale runs from White (best), through Off-White-to-White, Off-White, Cream, Light Tan, Tan, Brown, and Brittle. Page quality often affects market price independently of structural condition; a White-page 9.0 frequently outsells a Cream-page 9.4 on Bronze Age keys.
