website i got it from
dimensions and colours:
- a height of 38mm and a length of 70mm. An imitation firearm
with dimensions less than this is to be regarded as unrealistic
- transparent
- bright red
- bright orange
- bright yellow
- bright green
- bright pink
- bright purple
- bright blue. -- not sure but i kept hearing that blue was taken off the list? so could be an out of date link but wouldnt imagine the other colours have changed.
i also noticed this :
13. An imitation firearm the principal colour of which is not one of those listed
in the Regulations does not automatically fall to be regarded as realistic,
although it is more likely that that will be the case. In these circumstances, the
general test of whether it is distinguishable from a real firearm, taking into
account its size, colour etc, should be applied. It is worth keeping in mind that
the intention behind this measure is to stop the supply of imitations which look
so realistic that they are being used by criminals to threaten and intimidate
their victims.
imo this makes the white gun a case of at the sellers disgression on wether they regard it as a rif or not although obviously most retailers will take the safe option to avoid hassle, it still could be argued that it doesnt count as a rif as i dont know many people who would treat a white gun any different to a blue/red/green etc
