Compose styles
Rather than blending styles toward a middle, this gives them roles. The first one carries the structure, the next comes in as the accent, and anything after that shows up in a single detail. Where they fight each other, it says so before you start.
How to divide the work
- Composition
- Follow GitHub Primer: Separate lists, tabs and sidebars with fine rules and hold spacing to a small token set
- Type
- Set in GitHub Primer's manner (Use one plain sans for body and labels; build hierarchy through weight and color), and let Mozilla Protocol's lettering (Use short heavy headings, readable body text and room for translation expansion) appear only where you want the eye to catch.
- Material
- Ground in GitHub Primer's material (Start from neutrals; reserve blue for links and semantic colors for success, warning and danger); bring in exactly one thing from Mozilla Protocol (Ground the page in black and white, reserving gradients for a single focal area).
- Colour
- Build on #F6F8FA, #0969DA, #24292F and admit one accent from #FFFFFF, #7542E5, #20123A.
Where they fight
- GitHub Primer and Mozilla Protocol both belong to Platform Screen Languages, so the difference is small. Push the roles further apart than feels comfortable.
Caution
- GitHub Primer Adding borders and tiny controls to look like GitHub only creates a cramped admin screen when the work has no clear priority.
- Mozilla Protocol Spreading the Firefox gradient everywhere buries the content. Color should reinforce meaning and focus.
Image prompt
Produce four original images that take their structure from GitHub Primer (style, 2017–) and their accent from Mozilla Protocol (style, 2017–). ## What to make Make the kind of thing GitHub Primer exists for: developer SaaS and admin tools that must hold many states and actions on one screen, or keeping information density and accessibility consistent across product teams. Choose one subject and hold it across all four. ## Structure comes from GitHub Primer - Neutral surfaces with blue links and restrained status colors - Octicons paired with short action labels - Thin borders separating lists, tabs and sidebars - Consistent steps of type and spacing even at high density Composition: Separate lists, tabs and sidebars with fine rules and hold spacing to a small token set. Type and lettering: Use one plain sans for body and labels; build hierarchy through weight and color. ## Accent comes from Mozilla Protocol, used sparingly - Bold black headings and broad white space - Large fields of vivid color - Flexible billboards and cards - Short copy and explicit calls to action Let one material quality come from it: Ground the page in black and white, reserving gradients for a single focal area. ## Colour and feeling Build the ground on #F6F8FA, carry the structure in #0969DA and #24292F, and let a single accent come from #7542E5. These are read off real works, so a direction rather than a fixed palette. Feeling to carry: technique, trust, calm, exhilaration. ## Where they fight - GitHub Primer and Mozilla Protocol both belong to Platform Screen Languages, so the difference is small. Push the roles further apart than feels comfortable. ## What goes wrong - GitHub Primer: Adding borders and tiny controls to look like GitHub only creates a cramped admin screen when the work has no clear priority. - Mozilla Protocol: Spreading the Firefox gradient everywhere buries the content. Color should reinforce meaning and focus. ## Across the four Keep the roles fixed in all four. Vary the framing, the scale and the arrangement so the set shows what this pairing can do rather than four versions of one picture. ## Constraints - Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work. - Do not reproduce the composition of an existing work. - Produce original compositions in the general period languages described above.
