The Scout Association issued new brand guidelines in May 2018 (https://docs.scoutsbrand.org.uk/guidelines.pdf version 1.0) and version 6.0 of the theme supports these new guidelines.
The ten colours in the 2018 brand guidelines are white, black, Scout Purple, Scout Teal, Scout Red, Scout Pink, Scout Green, Scout Navy, Scout Blue and Scout Yellow. The brand guidelines suggest that they be used as pairs of colours in the order just listed (e.g. Scout Green with Scout Navy). The guidelines also show five shades of grey (5%, 20%, 40%, 60% and 80% black).
The Beavers 'blue' logo and the Cubs 'green' logo appear to have changed colour to the new definition of Scout Blue and Scout Green but the Scouts section logo, which was in a dark teal, doesn't appear to match one of the new colours.
In order to ease the transition the theme will continue to support the fourteen colours (excluding white and black) that were featured in the brand guidelines issued in 2015 and discussed below.
The ten 2018 colours will always be presented first and will be used for all default colours in the theme, with the exception of two of the 'boxes' on the home screen which are coloured to match the Scouts section logo.
Starting with version 4.0, the theme only used the sixteen colours defined in the 2015 brand guidelines (except for a pale background colour used for contrast in lists which is replaced by grey in version 6.0). Previous versions had combined the colours in the two editions of the previous guidelines and had not included the colours used in the separate section guidelines that were published prior to 2015.
Unfortunately the 2015 guidelines didn't give names to the colours such as 'Scout Purple', so within the theme options the colours are referred to by their Pantone number and an informal colour description.
The colours are called white, black, yellow, orange, red, brown, mauve, purple, blue, dark blue, turquoise, teal, dark green, medium green, green and grey.
The 'core' colours were purple, green, grey, black and white. These were identical, or close to, the colours in the previous guidelines. They were intended to be used in 'corporate' and adult facing material. The other colours were intended to provide the palette used for the section logos, uniforms and badges though the shirt colours for Explorers, adult members and Active Support did not appear to be included.
