I've experienced that a German GS-certification body did not allow red coloured functional buttons on Information Technology Equipment (ITE) even though IEC950 amd.3 clause 1.7.8.2 allows you to do so. They based their verdict on a descision in an organisation called EK14 (which I'm sure that the GS members could tell you more about). The EK14 descisions should be common practice for all the GS members as far as I know.

Red is reserved as an "emergency" or critical safety color. However, some standards (such as IEC 950) allow red indicator lights if there is no confusion as to their meaning. Usually panel indicator lights are labeled so this eliminates the confusion. Patty Elliot TUV Rheinland of N.A.
