Colour
Usage rules
Forest Green leads. River Blue supports. Signal Red is an accent, never a background for long text. Meadow Green is the one colour that cannot carry type.
Forest Green
Safe as text on white at 9.93:1.
River Blue
Safe as text on white at 8.86:1.
Signal Red
Safe as text on white at 5.01:1.
Meadow Green
Only 2.87:1 as text on white, below the 4.5:1 minimum. Use it as a fill or a swatch, and set type in the darkened variant instead.
The swatch always renders the exact brand hex. Where a colour cannot carry text, only the type changes, never the colour being documented. Neutrals carry body copy: Ink for headings, Slate for supporting text.
