01 / THE IDEASOLa CORPORATE DESIGN
Software that
grows with your
organisation.
SOLa gives a business a system it can make its own.
The cell is the starting point: a defined space for its data, workflows, and change. Cells can share capabilities while retaining their own authority.
The existing circular cell mark carries that idea. Coral gives it recognition; navy and Roboto give the surrounding material a clear, consistent frame.
The headline and ownership phrase come from the existing HHFL pitch. Layout and usage recommendations in this guide are drafts.
Connected
Use round cells and explicit interfaces in diagrams. Keep independent entities visually distinct.
Deliberate
Use the existing artwork, sourced colors, and Roboto consistently. Make every element earn its place.

02 / THE EXISTING IDENTITYCANONICAL ARTWORK / UNCHANGED
The SOLa
cell mark.
The existing logo uses a coral circular boundary and an organic S-shaped path. Retain its curves, rounded stroke, opening, proportions, and original color.
SOLaUse the actual artwork
Use sola_cell_mark.svg from the brand folder. The work-folder copy matches it byte for byte. Keep the artwork intact.
Give the mark space
Draft guidance: clear space of ¼ mark diameter. Start at 32 px on screen or 10 mm in print; proof it at final size.
Keep the source color
Coral #FD6B4E. Use a white or navy field. The SOLa text here is a layout setting in Roboto, not a newly invented logo file.

03 / SOURCE COLORSEXISTING DOCUMENT PALETTE
Coral at the center.
Navy for structure.
These values come from the existing logo and SOLa’s short business-plan template. This guide uses that document palette consistently; pitch-specific colors are recorded separately.

Existing pitch family. HHFL uses blue #346E8C, teal #297B73, and violet #77628F. These are presentation-specific colors, not replacements for the coral logo. Keep the palette of a given document coherent.
Readable combinations. Navy on white: 18.1:1. White on blue: 8.4:1. Navy on coral: 6.4:1. Coral on white is 2.8:1: use it for the logo and decorative accents, not small text. Values are digital RGB; proof print colors with the selected profile.

Roboto is already used in the business-plan templates and HHFL presentation. Use the existing family across the guide, documents, and product studies.

Use short, left-aligned headlines.
Space to understand.
Body: 16–18 px · 1.55 line height
Limit text to about 65 characters a line.
Review the change.
Use medium weight for labels and controls. Let spacing and weight establish hierarchy.

05 / GRAPHIC LANGUAGEROUND CELLS / EXPLICIT CONNECTIONS
Start with
the cell.
The logo and existing pitch diagrams use round boundaries. Keep that visual language: an independently scoped cell, its own contents, and a deliberate connection to another cell.
01 / Bound the cell
A round boundary denotes an independently scoped operational cell.
02 / Name the interface
Connect at boundaries. In an actual architecture diagram, label what crosses.
03 / Distinguish the parts
Rectangles represent artifacts. Keep them distinct from running cells.
Existing notation. Use Cellmark for architecture, dependency, and transfer. Its editing guide distinguishes cells, artifacts, external systems, and ports. These three sketches illustrate that vocabulary.
Draft layout guidance. Use an 8 px spacing unit, generous margins, thin rules, and left-aligned text. Keep diagrams readable; split them before shrinking labels.
