The Proteus brand playbook

This guide includes the elements you need to create branded materials for Proteus - from Powerpoint presentations to social posts. If in doubt - or if something's missing - drop the Marketing team a shout.


Our brand isn’t for our benefit. It’s designed to help prospects and clients recognise who we are and what we stand for. That’s why consistency and attention-to-detail matter: our brand speaks for us before we have the chance to speak for ourselves.

When we all use the same elements and templates, we build a consistent brand identity – regardless of what we’re saying or who we’re communicating with.

Here, you’ll find a mix of design elements and templates to help you create on-brand communications.

The basics – our logo, fonts and colours


We have black and white versions of our logo, suitable for dark or light backgrounds. We don’t have fixed rules about logo spacing – just ensure to leave some space around each edge, as shown above.

We also have a black ‘favicon’ (the single ‘P’) which we use for social media and site tabs, among other things.


We have two different brand fonts – one for headings, and one for main/paragraph text. Most of our templates are pre-populated with these, but it can be useful to know what the fonts are and when to use them.

  • Our headline font is DINOT – a sans serif typeface with a soft, clean look.
  • Our main text font is Calibri – a modern sans serif typeface with rounded edges.



Why do we have two fonts? Well, we could have gone with Calibri across the board (being a Microsoft font, it’s available in all MS products), but that would have been a bit too simplistic. Most brands have 2-3 fonts, choosing a more stylised typeface for headlines as a way to give them standout.


As with fonts, these are pre-populated in our templates (PPT etc), but if you ever need to create something from scratch, here’s our colour palette with the relevant hex codes.

We don’t have hard and fast rules about how the colours should be used, but certain combinations work better than others. So try to stick to the background, text and highlight recommendations for most communications.

Examples of recommended colour combinations

Light background colourway

Dark background colourway


Examples of colour combinations to avoid

The grey background is less harsh than white, but be wary of the font colours you use on it – as shown below.


The ‘calm green’ can be used as a background colour, but works best with soft black or marine risk purple text, especially when the font size is small –  as demonstrated below.
