Design System — POC

Icon Style Evaluation

  • Status POC — For Review
  • Audience Gio & Multimedia Team

Design Review Not a Production Change

Purpose

Overview & Scope

This POC evaluates whether the current course icon set should be retained, refreshed, or replaced with a more modern icon system. It presents six icon styles side by side against a consistent set of learning activity and material concepts, and provides structured criteria and review questions to support a design decision with the Multimedia Team.

This page is a design evaluation tool. It does not change the production icon system. Any decision made here requires a separate implementation phase.

Icons Under Evaluation

The following concepts are compared across all six icon styles:

Learning Materials

  • Video
  • Reading
  • Assignment
  • Discussion
  • Test
  • Interactive
  • Audio

Icon Styles Compared

Current Lucide Heroicons Tabler Phosphor Custom

All are open-source and SVG-based except Custom (future concept).

Style Notes

Each icon library has a distinct visual personality defined by stroke weight, corner treatment, and icon metaphor choices. These differences become significant when icons appear small and in context with course labels and UI text.

  • Current — Lucide-derived, 2px stroke, round caps. Used throughout the V2 prototype.
  • Lucide — The current library, actively maintained. Compared using alternative icon selections for the same concepts.
  • Heroicons — By the Tailwind team. 1.5px stroke, more geometric. Strong accessibility track record.
  • Tabler — 5,500+ icons, 2px stroke. Highly consistent grid system. MIT licensed.
  • Phosphor — Six weights (thin to bold) plus duotone. More expressive; shown here at regular weight with duotone fill for select icons.
  • Multimedia Team Custom — Placeholder for program-specific icon concepts to be designed by the Multimedia Team. Highest consistency; highest production cost.

Side by Side

Icon Comparison

Each row shows the same concept rendered in six icon styles. Scroll horizontally on narrow screens. Icons are displayed at 24×24px — the standard size used throughout the template system.

Assessment

Evaluation Criteria

Each icon style is rated across eight criteria most relevant to a course design system. Ratings reflect how well each library meets the needs of a learner-facing educational product at scale. Custom icons are excluded pending concept development.

Rating scale: 1 = Poor  |  2 = Fair  |  3 = Adequate  |  4 = Good  |  5 = Excellent

Reviewer Prompts

Review Questions

Use these questions to guide your evaluation and capture feedback for the design decision. Write notes in the fields below or share responses in the review session.

Question 1

Which icon style is easiest to recognize without a label at 24px?

Question 2

Which style feels most modern and appropriate for a healthcare/allied health program?

Question 3

Which style best supports course navigation — helping learners quickly identify where they are and what to do next?

Question 4

Which style feels most professional for a presentation to accreditors, leadership, or prospective students?

Question 5

Which style would scale best across all course templates — from orientation pages to clinical practice modules?

Question 6

For Apply AI and Apply PULSE specifically — do any of the standard library icons adequately represent these program-specific concepts, or is custom icon design needed?

Question 7

Does the duotone approach (Phosphor) add meaningful visual hierarchy, or does it introduce unnecessary complexity?

Question 8 — Decision

Based on this review: should we keep, refresh, or replace the current icon system? If replace, which library is the preferred candidate?


Summary

Recommendation

The table below summarizes the strengths, weaknesses, and recommended use case for each icon style based on the evaluation criteria. A final recommendation follows.

Icon Style Strengths Weaknesses Recommended Use
Current
Score: 29/40
Already integrated across all templates. Team is familiar with the icon set. No migration cost. Slightly dated visual style relative to modern SaaS and edtech products. Some icon choices are less intuitive for learners. Mixed sources reduce consistency. Hold — Stable but Dated
Acceptable as-is for short-term use. Not recommended for long-term template investment.
Lucide
Score: 37/40
Direct upgrade path from current icons — same family, minimal disruption. Actively maintained with 1,500+ icons. Excellent consistency and coverage. Similar appearance to current set, so visual refresh may be subtle. Still a third-party dependency. Refresh — Low Risk
Ideal if the goal is improvement with minimal re-work. Drop-in replacement strategy.
Heroicons
Score: 39/40
Highest overall rating. 1.5px stroke gives a cleaner, more professional appearance at small sizes. Strong accessibility pedigree. Actively maintained by Tailwind Labs. Exceptional documentation. Smaller library than Tabler. A few edge-case concepts (PULSE, AI) have no ideal match and would need augmentation. Replace — Recommended
Best candidate for a full icon system refresh. Pairs well with the existing clean UI aesthetic.
Tabler
Score: 35/40
Largest library at 5,500+ icons — best coverage for future edge cases. Systematic grid design ensures near-perfect consistency. MIT licensed. Great if the template system expands significantly. Slightly more technical/engineering aesthetic. Less personality than Heroicons for learner-facing context. Density of options can slow icon selection. Replace — Alternative
Strong choice if library breadth is the top priority. Better fit for complex tools than learner-facing course pages.
Phosphor
Score: 32/40
Unique multi-weight system allows visual hierarchy. Duotone variant adds depth without adding complexity. Strong for branded or premium course experiences. Duotone at small sizes can reduce legibility, particularly for learners with low vision. Six weight variants increase decision overhead. Less commonly seen in edtech products. Selective Use Only
Consider for marketing or hero moments. Not recommended as the primary icon system for all templates.
Multimedia Team Custom
Score: TBD
Maximum brand alignment. Could represent PULSE, Apply AI, and other program-specific concepts precisely. Highest differentiation from competitor products. Requires design, review, and production time for every icon. Must be maintained in-house. Risk of inconsistency if not governed with a strict style guide. Phase 2 — Augmentation Only
Design custom icons only for concepts with no adequate library equivalent (PULSE, Apply AI, program-specific labels).
