Original sentence: A colour palette of 27 colors was supported, derived from RGB colour space with each component assigned as either off, half on or on.A number of these (as well as several subsequent releases) were tagged with the Roland name, in an attempt to give the CPC a recognisable mascot.Improvements were made to the video display which saw an increase in palette to 4096 colours and gained a capacity for hardware sprites.The Amstrad CPC 464 sold approximatley over 2 million units.The later Plus models extended this to 4096 colours and added support for hardware sprites.The law was subsequently changed to include machines with more than 64 KB RAM so a localised version of the 472 also exists.This allowed complete  customisation of the function of the machine, something that research labs and enthusiasts exploited for all manner of purposes
