Aristotle 25 Experience & Interface Guidelines translated into a concise portfolio case-study narrative.
A Shared System For A Larger Product Ecosystem.
The work centered on turning recurring interface decisions into a usable foundation. Instead of treating every product screen as a one-off, the guideline system gave teams a clearer way to make consistent decisions.
The challenge was consistency without adding complexity.
Aristotle’s product surfaces needed a shared language for color, component hierarchy, and accessibility. The system had to be clear enough for designers and developers to apply, while staying flexible enough for different product contexts.
Define principles that guide product decisions.
Modernize brand colors for application use.
Clarify when and how utility colors should communicate status.
Document action hierarchy for buttons and navigation patterns.
Three Principles Kept The System Practical.
The guidelines are anchored by three plain-language principles. They make the system easier to explain because each principle connects directly to user value, product usefulness, and ongoing learning.
Intuitive
“If it’s not obvious, it doesn’t do the job.”
The system reduces the learning curve by making interface behavior predictable, clear, and easy to scan across product surfaces.
Useful
“If it doesn’t do the job, it doesn’t matter.”
Guidance is tied to real user tasks, with accessibility treated as a baseline requirement rather than a late-stage polish pass.
Innovative
“If we’re not learning, it is obvious.”
The guidelines leave room for feedback, iteration, and product evolution while keeping teams aligned around common decisions.
Color Guidance Made Brand And Status Decisions Easier.
The color system separates brand expression from functional feedback. Primary and secondary brand colors provide identity, while utility colors communicate information, success, warning, error, tint, and neutral states.
#006AC0
Primary Blue
The main Aristotle interface color for important brand expression and high-value interface moments.
#CF460B
Secondary Orange
A warm secondary color used to add emphasis and contrast without competing with the primary blue system.
Accessible Status Use
The system notes that color alone should not indicate feedback status. Utility color should be paired with clear language and, where useful, an icon so the state is still understandable without relying only on hue.
Buttons And Navigation Turned Guidance Into Reusable Patterns.
The component layer translates principles into repeatable interface behavior. Button hierarchy clarifies action priority, while the menu pattern demonstrates how dark navigation surfaces can stay structured and readable.
Primary Actions
The guidance keeps the most important action singular in a context whenever possible, reducing competition between calls to action.
Secondary Actions
Supporting actions are grouped around the primary action so users can understand hierarchy without extra explanation.
Icon Support
Buttons can include one icon before or after the label, helping users recognize common actions quickly without overloading the control.
PDF guideline screens
Additional Screens Show How The System Handles Everyday Product UI.
The PDF guidelines also documented practical screen patterns for tables, forms, dialogs, and alerts. These examples make the system easier to apply because teams can see how the rules translate into common product moments.
Tables
A simple table pattern for scanned record groups and compact row actions.
Forms
Input states, grouped controls, dropdown starts, and clear form feedback rules.
Dialogs
Modal and off-canvas guidance for focused tasks without losing page context.
Alerts
Status-message variations that pair tone, text, and visual treatment for accessibility.
The Outcome Was A Clearer Foundation For Product Teams.
This portfolio version keeps the case study intentionally concise. The value is not in showing every rule, but in showing how the system connects principles, tokens, accessibility, and components into a shared way of building products.
Shared Language
Teams gained a consistent vocabulary for brand color, utility color, action hierarchy, and interface behavior.
Accessibility Baseline
The guidelines make accessibility part of the system by pairing color feedback with text and icon support.
Scalable Direction
The system gives product teams a practical foundation that can evolve as feedback and product needs change.
