Abstract first
No letters, numbers, or terminal symbols. Just a shape.
Sourcefour identity
Two equal shapes, offset so they meet at one edge. A simple stand-in for comparing two states of the same history.
The mark
No letters, numbers, or terminal symbols. Just a shape.
Both shapes are the same size. Neither one is the original.
Two shapes and a gap, still clear at 16px as a favicon.
Graph palette
The logo uses the same two colors as the first two lanes in the commit graph. No separate marketing palette.
Reduction
Keep both forms equal and preserve the diagonal gap.
Do not stretch, rotate, outline, or reconnect the forms.
Do not introduce colours outside the product palette.
