Logo usage
In most circumstances, the OPC logo must have prominence over and

X

above other images and graphic elements. Where possible, the logo must be 
placed at the top of the item it appears on and other logos, text or images 
Z
must not be placed above or to the left of the logo. An individual logo must 
appear only once in a document.

An isolation zone has been established to ensure that the dignity of the logo 
is not jeopardised through crowding. The location of this zone is indicated 
X

by the grey Xs in the illustrations below. The width of ‘X’ is the distance 
X

between the top of the capital ‘A’ in ‘Australian Government’ and the 
bottom of the horizontal line beneath these words (as indicated by the red 
Zs in the illustrations below). That measurement will vary depending on 
the size of the font used in the particular case. Please note that the isolation 
Z
zone shown here must be seen as a minimum and can be greater; and that it 
applies to every form of the logo and in every application of the logo.

Minimum size:
The minimum width of the Commonwealth Coat of Arms on stationery 
and larger items must be 20mm. However, on items such as name badges 
and identity cards where it may not be possible to adhere to this, the Coat 
of Arms may be altered.
20mm

Logo usage
The logo must not be used as decorative or artistic 
element or as a watermark, and must not be 
overprinted with text or images.
Guidelines for limited colour use have been 
developed. The logo can be reversed – white on black 
– or can appear as a light colour on a dark colour (e.g. 
dark green, black, etc) or as a dark colour on a light 
colour. It is essential to ensure that any use of colour 
does not compromise the integrity of the logo. The 
logo must not appear in a pastel or light colour on 
a light background colour, or as a tint, gradient or 
stipple of any colour. The logo must not appear as a 
dark colour on a dark background.
The various elements of the logo must not be 
represented in more than one colour.
Use of a black and white logo on a particular product 
does not preclude the use of the logo in a different 
colour palette on other products.

Colour palette
PRIMARY COLOURS
The OPC colour palette is professional yet contemporary. The primary 
colour is dark teal, with lighter shades of teal, light teal, grey and 
maroon as accent colours. The dominance each colour occupies in the 
60% TINT
palette is shown through their hierarchy on the right, along with the 
RGB, CMYK and HEX values. Care must be taken not to overuse the 
secondary colours as they could change the tone of the brand.
If there is a need to create new design assets, tints of the primary colours 
RGB 8, 77, 94 
can be used if needed to create faded background graphic elements or 
CMYK 94, 59, 47, 30 
HEX #084D5E
background colours for text heavy documents. However tint should 
20% TINT
be used sparingly, only as background elements or colours, and should 
never replace the primary and secondary colours in terms of brand 
representation.
 
The teal primary colour and maroon secondary colour can be used to

Accessible text combinations
For people who are vision impaired, certain colour combinations of 
Light teal text on dark 
White text on dark 
text on coloured backgrounds can be hard or impossible to read. It

is currently standard practice to ensure digital assets produced are 
inclusive of accessible needs and diverse audiences. The WCAG 2.0 
CONTRAST RATIO 6:1 
CONTRAST RATIO 9.4:1
level AA standard is the general benchmark to test if digital assets are 
accessible or not.

Typography
The primary typeface of OPC is Open Sans, a clean 
HEADINGS
and modern sans serif. Open sans is professional yet 
modern, reflecting the OPC brand. It should be used 
Open Sans Extrabold
for headings and subheadings only. However for 
banners, social media and signage either font can be 
used to achieve the desired visual result.
Open Sans Bold
EB Garamond is the complementary font to Open 
Sans, it is a classic serif font which has been adapted 
Open Sans Semibold
for digital use, with high legibility and readability. EB 
Garamond should be used for body copy only.

Graphic elements
Additional visual elements help to bring the OPC brand 
Graphic element 
to life, these include three abstract shapes inspired by 
inspiration
the text “OPC”. These shapes can be used in a variety of 
ways to create graphics which can add visual interest to 
documents and presentations. Some examples of how 
the shapes can be arranged are shown on the next page.
The shapes can also be blown up and used as containers 
for photography, as shown in the sample applications on 
the next page.
Do not overuse these graphic elements when creating 
new design assets, there should be sufficient white space 
in any given layout, giving the content room to breathe.
