Our hob gas usually burns blue, just yesterday for a short while it was burning bright orange on all rings. I assume an inpurity in the gas, after 5mins it was burning blue again.
Is anyone able to offer an explanation about why this happened?

Gas while burning does not get sufficient oxygen / air, it burns with yellow flame. If it gets sufficient oxygen / air , it burns blue.
The flames on most burners that use a gaseous fuel such as natural gas or liquified petroleum gas should burn steadily with a clear, blue flame, except for special designs such as fireplace logs and torches. A wavering, yellow flame on a normal gas burner indicates that the burner is out of adjustment or the air inlet is restricted. As a result, the burner may be producing excessive amounts of CO. However, the flames in burners that use fuel oil should burn with a clear yellow or orange flame . This is an indication of good combustion in equipment that burns fuel oil.

Either an impurity or a slight blockage to the air vents leading to excess carbon in the flame, leading to that bright orange color. If the vents got a temporary block, it can happen.

it didn't have a sufficient supply of oxygen. This can be caused by a simple thing such a normal salt (sodium chloride).
