Version 4.0 onwards of the theme only uses the sixteen colours defined in the 2015 brand guidelines except for some limited use of a very pale background colour to provide some contrast with white in things like lists of posts. Earlier versions combined the colours in the two editions of the previous guidelines and did not include the colours used in the separate section guidelines. There is now only one set of guidelines.
Unfortunately the guidelines no longer give names to the colours such as 'Scout Purple'. Within the theme options the colours are referred to by their Pantone number and an informal colour description.
The colours have been called white, black, yellow, orange, red, brown, mauve, purple, blue, dark blue, turquoise, teal, dark green, medium green, green and grey.
The 'core' colours are purple, green, grey, black and white. These are identical, or close to, the colours in the previous guidelines. They are intended to be used in 'corporate' and adult facing material. The other colours are intended to provide the palette used for the section logos, uniforms and badges though it is noted that the shirt colours for Explorers, adult members and Active Support have not been included.
