so I have had a restriction put on my license meaning that I can do night flying (and I assume IMC)
I'm not partially colour blind, nor do I have restrictions on my licence, but I can't fly at night or in IMC without the relevant training and qualifications
The licence
per se doesn't make the flying safe or unsafe; it depends who is flying the aircraft, and the conditions
I suggest you run your questions past your instructor at Biggin, and get their opinion
