Colour spaces describe how the red, green and blue primaries are mixed to form a given hue in the colour spectrum.

RGB colour space - Red, green, blue; the additive colour model used in digital images and displayed on a monitor.

Every file gets a final adjustment in Lightroom and then images are processed as full-size 16-bit PSDs in ProPhotoRGB colour space, because it’s the largest colour space available and the closest thing to maintaining the gamut of RAW.

A device independent colour space used to create consistent color whatever the device used to create or output an image, such as a monitor, printer, computer, or scanner.

The new approach to compression as well as colour space and colour conversion offers a lot of flexibility and the transformation process is entirely reversible, as all colour representations are transformed to an internal colour representation.

PROFILE - Refers to specific colour settings to be used with different papers and ink sets, to create the correct colour reproduction. It is used to transform from one colour space to another.

1 of that standard covers "Colour management Default RGB colour space sRGB." Being international, the wording of the standard uses "colour" rather than the Americanized "color," but the meaning is the same.
