Spectrum colour-coded officers, such as the field agents of higher ranks, (Captains,  Lieutenants), commanding staff officers (like Captain Scarlet, Colonel White, Lieutenant Green, etc.) each have a uniform wearing the colour of their codename - which in turn serves to hide their true identity for security reasons.  The uniform is composed of a colour-coded tunic, boots and cap (Scarlet, Blue, Green, White, and so on), with the rest of the uniform being of a charcoal black colour. Captain Scarlet here will serve as our model for the description of the colour-coded uniform.  Spectrum uniforms don't have rank or insignias on them (aside from the Spectrum logo),  for the same security reason as for the codename.  But the higher ranks can be recognized by their colour-coded uniforms.

1. Colour-coded tunic.
2. Charcoal  turtleneck jacket.
3. Colour-coded cap.  The side and the top are black with a glass visor (13), and the micro-transmitter radio (12).
4. Colour-code high boots. 
5. Charcoal  trousers.
6. Black belt, with silver buckle.  Hold the black holster (9), in which is the Spectrum issue colour-coded handgun (8).
7. Spectrum rainbow logo, on the sleeves as well as on the front of the cap.
8. Colour-coded handgun.
9. Holster, on the right hip.
10. Tunic pocket, on the left side.
11. Flashing epaulettes.  Spectrum epaulettes don’t serve to indicate rank, but rather as a communication device, in conjunction with the radiocap (12).  They would flash to the colour-code of the officer who is trying to communication… or they would flash white, in the case of the Spectrum Control, in Cloudbase.
12. Radiocap transmitter, on the left side of the face.  It will put itself in position when communication is achieved.  For more details on the Radiocap, go to the Radiocap page.
13. Glass visor.

 

Not seen:  part of the uniform also includes a Spectrum issue watch, on the left wrist.  

NOTE:  For some odd reason, Captain Black's tunic has white zips and belts. It can be extrapolated that it might denote a still higher rank than the other captains which with he serves when he was member of Spectrum.  Captain Black, after all, was capital to the formation of the organisation, the building of Cloudbase, and the training of those who will become his colleagues.
