# Chroma key > Removing everything of one specific colour from an image, such as a green screen or a coloured stand. Also known as: chromakey, chroma keying, key colour. Category: Photography techniques. Chroma keying removes all areas of one chosen colour from an image and makes them transparent or replaces them. It is best known from green screens; in product photography it removes stands, holders and supports painted in a colour that does not appear in the product. ## How PhotoRobot uses it PhotoRobot Controls uses chroma key operations to remove mannequin poles, nylon ropes, clamps and holders, for example to create the [ghost mannequin effect](https://www.photorobot.com/glossary/ghost-mannequin-effect). The operations are saved in presets so they run automatically for similar items. ## See on photorobot.com - [Image editing tools: chroma key](https://www.photorobot.com/software/image-editing) ## Related terms - [Background removal](https://www.photorobot.com/glossary/background-removal): Separating the product from its background so it can be placed on pure white or transparency. - [Ghost mannequin effect](https://www.photorobot.com/glossary/ghost-mannequin-effect): An editing technique that makes the mannequin disappear so the garment looks worn by an invisible body. - [Suspension mode](https://www.photorobot.com/glossary/suspension-mode): CUBE configuration that hangs a product in the air and rotates it, for items that cannot stand on a plate. - [Freemask](https://www.photorobot.com/glossary/freemask): PhotoRobot background removal from a front-lit and a back-lit silhouette shot of the same angle. ## Where this term appears on photorobot.com Mentioned on 26 pages.
